2. It's ad-free. Speaking of that clutter, how about those Facebook ads? They even appear in the iPhone app news feed now, and they couldn't be more obnoxious.
The Jewelry Sheller and Hester & Pearl, because I know how invasive they are. Some might call me a fool, say that's just the way it is, blah blah. My feeling is that there has to be a better way to advertise within your social network.
3. Control. With the Circles feature, I can choose exactly where I want to share the material I post. Circles are awesome. I can arrange my friends/family/acquaintances into categories, and when I share something, I can control who sees it down to specific, individual people.
4. The mobile app is great. It has almost full functionality compared to the desktop version. The only thing I wish it had was the ability to post from, or utilize business pages. If it's there, then I haven't found it yet. My re-entry into G+ was a Hangout (which is another really cool feature) with some friends from college, and I was able to participate from my iPhone.
5. Communities. This is, I think, a relatively new feature. With Communities, users can find people with the same interests as them and share links, have discussions, etc. Some of the groups are free to join, and some require users to "request to join."
If you'd like to read up more on G+'s features, this is a great infographic I found from Mashable. How do you feel about Facebook? Is it getting on your nerves? Would you consider a switch to Google+? I'd love to gear your thoughts.
