So far, I've really enjoyed using Google+.
The biggest challenge I've had is that the people I'd like to interact most with are not currently using Google+, which depresses its overall utility for me.
On the other hand, I've been able to utilize Circles effectively to spotlight the content that I want to see most of all.
Yes, I DO worry that any outfit like Google can instantaneously erase all of your online content, for any reason or no reason at all, particularly with the lack of any appeal mechanism, but I cautiously continue to use, and like, the service!
