Google + is like no other social network out there, and it's been great for promoting my blog, most of my early readers probably wouldn't even be reading the blog had they not found out about it on Google +.
I love how it's such an open format, and it's easy to share posts, and add people, with Google + "circles", you can send an invite to up to 500 people from a shared circle with two clicks.
What I really enjoy about Google + is the variety of people, and the fun I have interacting with them about the blog, anything I re-share from popular posts, and even my own personal rants in status lines.
Case in point is this, I put up a status ranting about the fact some of my followers were getting hit by what I like to call "report Nazis" , an obnoxious group of people who have nothing people to do than to get overly offended by people's post, and report them for it, causing Google to censor their posts. These people don't have the decency to simply remove people from following and/or block them if they don't like their posts, instead of reporting, and they're too cowardly to admit it was them when it happened.
Well, one Google + follower decided to be offensive as she could be, out of spite of these cowardly reporters, and the resulting conversation took a hilarious turn, with several other people joining in.
Eventually the post ended with a serious discussion on religion, but before it did, the content though funny, is not for the easily offended.....
I love my Google + followers! :)
