How do you change your name now

I don't get Google Plus Communities.

Instead of making it easier for users to publish stuff, now a user must also think of where to publish stuff. Users already have tons of platforms, from facebook and twitter to blogs to local forums to news comments.

Content is king. Let users publish anything on G+ (or anywhere else) and categorize this data using Google's great search engine.

Let followers define the people they follow and their interests - general and specific to certain people - and do the intersection for the followers.

+Vic Gundotra, thoughts?
