First Buzz. I've read that this is a lame attempt by google to get into social networking, i.e., facebook. I have a facebook account but still have not used it much nor seen any real value, plus I find it cluttered and confusing. Who are those people?
The integration that google has done so far seems much better than that described by pundits and I would be much more inclined to extend my use of google services than those in facebook and that ridiculous twitter.
