I joined Google Plus last week. I like the layout and the interface- seems easy to navigate and I've appreciated most things Google (gmail, maps, etc.). However, I don't know if it will replace Facebook. I'm not even sure it is supposed to, but kind of has that feeling. Plus, (pun intended) who still keeps up with MySpace? Maybe this is the natural progression of social media. If you'd like a decent rundown on all of the cool features of Google+, read this article.
