Facebook sucks. Twitter is too restrictive. LinkedIn is a bunch of bovine feces. It would seem that the only reason we use so many social networks is because each of them cannot be all things to all people. That being said, the only network that, for me, has the most going for it is Google+. If you have a Google account (Gmail, Youtube, Drive, etc.) I would suggest that you try it out. The interface is fresh, clean, and novel. Coming from the previously mentioned social sites, you have to take a minute to reorient your brain from a vertical perusing style to a more fluid approach. Also, this interface highlights activity from your actual meatspace friends.
