I like Google+
I like any service that uses special characters in its name.
That's why I loved Yahoo! so much. It was exciting. But that was 30 years ago, and a lot has happened since then.
I'm definitely using Google+. I haven't been as heavy a user as I normally am with new services because I'm finishing my book writing in the next week, and I've found that using Google+ is highly negatively correlated with getting important things done.
