mhhfive - Good point about Facebook. I guess I expect more from Google+ because it's already pretty bloggy. Seems to need just a little push to get all the way there.
A friend once asked me whether Google+ is a threat to Facebook. She seemed surprised when I responded, no, it's more of a threat to Twitter.
As long as Facebook is the place where my non-techie friends and family hang out -- real life friends and family, people I've known for decades -- I'll be there. Twitter, however, has evolved into a community of interest. I have some RL friends, family, and colleagues there, but it's a place where I look for interesting content, not news from friends, colleagues, and family. And Google+ is like that too.
