I'm liking the ideas behind Google Plus, but there's a few two many fidgety things or elements missing. For example, I have to use another browser to see what my public profile looks like when other sites lets you view it logged in, and you should be able to add and removed more elements from your profile. There a bit of a nerdy feeling to the overall structure, or maybe it's trying too hard in places and in others it's just not as easy as Facebook or even Linkedin.
Nice, but Google must try harder.
Also Circles would have been a better name.
