Google vs. Facebook and Bing (again)

Almost a year ago, I wrote about semantics and social networking as threats to Google.  In that post, I referenced a prior article on investments in natural language processing, such as Microsoft’s acquisition of Powerset, which is now part of Bing.

Today, there are two articles I recommend.  The first addresses the extent to which Google’s Superbowl ad is a response to the threat from Bing.  The second addresses Facebook overtaking Google.
