One story that’s capturing a lot of attention today is Facebook surpassing Google in time spent on site in the U.S. Silicon Alley Insider has a chart illustrating as much. 

While this is certainly good news for Facebook, it doesn’t necessarily mean bad things for Google. These two are increasingly becoming bigger competitors, but Google, at least the search engine part, doesn’t always aim to keep users on its site. Sure, it does to some extent with things like Google Places and hosted AP articles, but the release of Google Instant this week clearly shows that Google wants to get users what they’re searching for faster. 

That’s not to say that Google doesn’t want users sticking around. I think we’ll see more direct answers coming from Google itself in its search results. Google Squared is a big part of this. 

Speaking of Google Instant, Danny Sullivan has an interesting article about the company disguising relevancy issues with the feature. Also, I have another article up about Google Instant’s effect on web history, and how it might work from the browser search box and Chrome address bar.

Caitlin Fitzsimmons reports that Facebook has filed for a patent on social CAPTCHAs. The title is "USING SOCIAL INFORMATION FOR AUTHENTICATING A USER SESSION". The abstact says, "A social CAPTCHA is presented to authenticate a member of the social network. The social CAPTCHA includes one or more challenge questions based on information available in the social network, such as the user’s activities and/or connections in the social network. The social information selected for the social CAPTCHA may be determined based on affinity scores associated with the member’s connections, so that the challenge question relates to information that the user is more likely to be familiar with. A degree of difficulty of challenge questions may be determined and used for selecting the CAPTCHA based on a degree of suspicion."
