I hate Facebook. I love Twitter. I always wanted an in-between. I thought Tumblr would fill this but without people to interact with, it becomes noise. Tumblr is one way traffic whereas G+ seems to be filling the in-between. It has the users and a great UI. It's a long way to go yet until I use it to it's full potential but it's a step towards finding a place where I can interact outside of 140 characters.
I just hope people don't start posting pictures of their pets or what they look like wasted.
