Well I just used it, but it was in a generic sense. For me it's all about the human relationships and I'm seeing more of that here than I have anywhere else. Of course that could all change.
I get a little uncomfortable every time you call Facebook or Google+ a "social network". The social network is the relationships between you and everyone you know. FB and G+ are web sites... communication platforms that seek to capture your social network for profit. Granted, they are wonderful tools. But please, please, please don't confuse computer programs with real human relationships... which (hopefully) persist regardless of which web site is hot this week.
