John Pozadzides of the Web analytics company Woopra wrote a guest post for ReadWriteWeb looking at the web's top sources of referral traffic. He breaks it down in to the following categories: social network, social bookmark, search, and media.

Six versions of Google top the list for search before Bing makes an appearance. Facebook takes the cake in social networks, followed by Twitter and LinkedIn. In the social bookmark category, StumbleUpon leads, and in media, it's YouTube.

Mashable's Jolie O'Dell reports that a court in Komsomolsk-on-Amur, Russia has demanded a Russian ISP block access to YouTube because it hosted what it says is an extremist video. The Internet Archive and three online libraries were also reportedly blocked. As O'Dell points out, a number of other countries have also blocked access to YouTube at different times.

The New York Times reports that the House Financial Services Committee approved a bill that would effectively legalize online poker and other nonsports betting, overturning a 2006 federal ban.

Pocket-lint reports that Amazon claims ebook sales will overtake paperbacks next year. It's a pretty astonishing notion, but not too hard to believe considering that Amazon recently announced that ebook sales have overtaken hardback sales.

Mobile Crunch has pointed out that RIM has purchased the domain BlackPad.com, speculating that a long-rumored BlackBerry tablet could be called the BlackPad.

News surfaced yesterday that a directory containing personal details of over 100 million Facebook users has surfaced on a file-sharing site. BBC News spoke to the man responsible who says he harvested the info for a security tool.

Back in early May, it was discovered that Google had invested in something called Recorded Future. Now Wired reports that the CIA is involved as well, in the company that monitors the web predicts the future.

Facebook launched the long-awaited Questions feature yesterday (in beta). Search Engine Land has a detailed walkthrough of the feature.

According to Ben Patterson at Yahoo News, citing information from Courant.com, U.S. libraries are loaning more DVDs on a daily basis than Netflix and Redbox are renting them. This make sense given that many libraries offer free DVD loans, and cheap prices on new releases.

GM is working on a campaign to promote its 2011 Buick Regal and has launched a website called "Moment of Truth."

GM promises its Moment of Truth site will include all reviews and consumer opinions no matter if they are negative or positive.

"We are inviting consumers to find out on their own that Regal is a true performance sedan and worthy of their consideration," said Craig Bierley, Buick advertising director. 

"We are making it easy for the consumer to get unbiased opinions in one online location."

Moment of Truth will pull in content from a variety of social media sources and give users the ability to share via social networks.  It includes YouTube videos, Flickr photos, comments from Buick's Regal tab on Facebook, tweets from Twitter, as well as automotive reviews and blogs. Anyone can be a contributor to Moment of Truth by sharing their stories related to the Regal and posting them online.

Other elements of the Buick Regal advertising campaign started earlier this month in unconventional and traditional outlets. The campaign continues to build on advertising outreach that Buick started with the LaCrosse launch last year.
 

Search Engine Land Editor-in-Chief Danny Sullivan points out how poorly Google handles those gaming Google News, using Google Trends as a starting point.

Do you find Google News to be too heavily polluted? Share your thoughts.

He found a blatant example when the term "chocomize" became listed as "volcanic" on Google Trends. When clicking for the results, he found several sites serving Google ads that presumably only created posts about the term because it was trending (as a way to get some easy traffic, and potentially ad clicks). In fact, some examples came from sites that were clearly aimed at entirely different niches, such as a horror movies site and a TV/Anime site. The biggest problem from the user's perspective is that there was nothing immediately indicating why the term was trending.

The real reason the term was trending was apparently because CNN ran a story earlier in the day about a company called Chocomize that makes custom candy bars (a pretty cool concept, I have to say), but when looking at the Google News results, Sullivan had to really dig to find that story.

"The pollution within Google News is ridiculous," Sullivan says. "This is Google, where we’re supposed to have the gold standard of search quality. Instead, we get 'news' sites that have been admitted — after meeting specific editorial criteria — just jumping on the Google Trends bandwagon, outranking the actual article causing the term 'chocomize' to be popular, polluting the news results and along the way, earning Google some cash."

Earning Google some cash indeed. There is no doubt that this goes on all the time, specifically with AdSense sites. Interestingly, in a story grouped with Sullivan's on TechMeme, the Wall Street Journal has some words from Eric Schmidt talking about Google's famous "one trick pony". Schmidt is quoted as saying, "But if you've got a one-trick pony, you want the one we have. We're in the ad business, and it's growing rapidly. We picked the right trick." The piece goes on to talk about how that trick is going to pay off greatly in the mobile space as well, as more and more people gravitate to the Android operating system.

Schmidt has said in the past, as Sullivan reminds us, that the Internet is a cesspool (referring to an excess of useless content). So, to be fair, Schmidt doesn't come across as being very enthusiastic about the sites that take advantage of Google Trends to game Google News. Still, there is money to be made, and if sites meet the criteria of what it takes to get into Google News, there's a fine line Google has to walk, regardless.

Can it all be so simple?

Sullivan says, “It shouldn’t be that hard for Google to police what shows up in response to what it publishes on Google Trends. Spam sites ought to be nabbed. AdSense sites ought to be shut down. News publishers abusing the very lucky position they have of being in Google News, by routinely tapping into Google Trends topics that aren’t relevant to their publications, should get the boot.”

While I greatly respect Sullivan, and value his analysis and opinions, I’m not sure it’s as simple as that. We've all seen how the mainstream media sites turn to blogs to get their stories (sometimes without giving credit or links), just as the sites in question appear to have done with CNN. We spoke with Sullivan about this not too long ago after he became a victim of such a scenario.

It's hard to say that just because you use Google ads, you should be penalized. That's not to say there isn't an issue, but while there may be plenty of “garbage sites” there are some pretty highly respected publications that serve ads by Google. The horror movie blog pointed to, does appear to generally offer horror movie related news (while crediting sources), based on a quick glance of its most recent content.  But if the Chocomize story on that blog doesn't credit its source, that is a problem. Maybe this is a “garbage” site, maybe it’s not. From Google's standpoint, determining that can’t be easy in all cases.

Looking beyond the credit issue for a moment, when it comes to topic-spam, who’s to say what a publication would find of interest to its audience? I’m not sure that I agree that a blog mainly focused on horror movies, for example, should not be able to blog about chocolate or another off-topic subject every now and then. That’s up to the publication and whether they want to risk alienating their own audience, if you ask me. Again, I’m not saying Sullivan is wrong about this particular site’s practices. I’m just looking at the bigger picture.

Maybe Google could do more to look at story sources, but that's got to be a difficult task across all publications, and there would no doubt be plenty of room for debate between publications about who broke a story first.

I'm not saying this is what happened either, but hypothetically, what if the horror movies blog actually talked to the Chocomize people first and had the story first, and CNN just happened to find it and find it newsworthy themselves, and do their own piece. Now, that's an unlikely scenario in this particular example, but it's not outside of the realm of possibility in other examples, such as the one Sullivan experienced recently himself.

Regardless of that even, it's hard to say "you can't have content about this topic because we posted it as a trending topic."

There is clearly a problem with Google Trends. Sullivan is right in that the result doesn't help explain why the topic was trending. He's also right in that the original source (CNN) should be more visible. However, cleaning up the "pollution" might not be such an easy problem to conquer. It’s hard to say if Google is allowing such pollution to go on so it can make more money or if the problem is just too difficult for the search giant. It could be a combination of the two.

Groupon, the service that provides daily deals that save customers money, is getting a lot of attention these days. Now, they'll be getting much more. Late yesterday, the company announced a big feature in Personalized Deals. Today, they have released an FAQ for those.

"Personalized Deals is the biggest thing we’ve done since we launched Groupon," the company says. "While Groupon won't look much different, sending different deals to different users transforms Groupon in four big ways."

If you thought Groupon was getting big, this feature might be the ticket to making it a household name. Along with the launch of an Android app last week, Personalized Deals is likely going to put Groupon on a lot more people's mobile devices.

As a result of the Personalized Deals feature, users will start getting offers from a growing number of businesses, which are tailored to their location, preferences, and buying patterns.

"Groupon has become so popular with merchants that we can’t keep up with demand," Groupon says. "Over 35,000 merchants are queued to be featured on Groupon, and with 97% of our merchants wanting to be featured again, that list is only going to get longer. As a response to unmet demand, Groupon has become one of the most prolifically copied websites in the history of the Internet, with over 500 worldwide Groupon knockoffs appearing in the last 12 months."

There's no question that the Personalized Deals feature is going to continue to attract businesses to Groupon. Customers have more of a reason than ever to use the service.

Microsoft's cloud computing division has scored a significant victory.  Three of them, even, as this morning, the company was able to announce that Dow Chemical, Hyatt Hotels, and the University of Georgia will use Microsoft cloud computing solutions.

A Dow VP indicated in an official statement that Microsoft's experience and expertise contributed to his corporation's decision.  That's arguably a bit of a snub to Google, which is making every effort to catch up to and overtake Microsoft in this field.

Meanwhile, the CIO of Hyatt Hotels complimented Microsoft's flexibility.  Also, if anyone's counting, Hyatt said this development will affect around 40,000 deskbound employees, plus perhaps another 17,000 workers who don't have full-time access to a computer.

Finally, the CIO of the University of Georgia said, "With Live@edu, we believe we will have a best-in-class communications and collaboration infrastructure . . ."  And for the record, something like 85,000 University of Georgia faculty, students, and staff should be using of that.

Again, then, Microsoft has scored some big wins, and Google - with the delay in L.A. representing its most recent cloud-related headline - seems to have lost this round.

Microsoft's stock is down 0.06 percent at the moment, a little behind the Dow (which is up 0.07 percent), but ahead of the Nasdaq (which is down 0.28 percent).
