Google+ is defining a niche that's actually pretty cool. The communities that exist there (which you can post on much simpler than Twitter or Facebook) are fairly vibrant and way more engaging.<p>I'll admit that it somewhat sucks for personal social networking, but it's found a purpose in my life.
This has not been my experience with g+ at all. I went over this a bit in another thread, but I think it works great for keeping up with communities, almost as a mashup of reddit/twitter with less of the trolling/spam.
