I've been using Googe+ for a couple of weeks (maybe a bit longer) now. Unlike so many, when I first started, I didn't dream Google+ would really be in direct competition with Facebook. I most certainly thought (and still think) it could potentially fade out Twitter, especially with all the mess over there. But having used it for awhile, I actually prefer G+ over Facebook. Now that we have confirmation that G+ will have a Games Stream, I'm not so sure how long Facebook will be able to stay ahead or even keep up.
As of July 22nd, Google+ surpassed the 20 million user mark.
