I really like the potential of Google Friend Connect. The ability to add social network features to any web site is pretty cool. One problem that I have is that I have to change the way that I read information to take advantage of Friend Connect.
I normally read blogs through Google Reader. When I do this, I miss all of the social enhancements provided by Friend Connect. What would be cool would be if Google Reader could present a Google Connect widget if you are reading a feed where the main site has the widget installed. Then you would be able to see what other users are reading.
