I have/have had an account with almost every conceivable blogging platform and email service etc. If any of my friends have it I'd sign up just try but I usually abandon accounts after a few weeks from the lack of network/replies. I'm on incessantly 9gag and Failblog, Facebook and Twitter and Pinterest, I post original content on Tumblr. I also have accounts with Lookbook, Fictionpress, Goodreads, Youtube, Etsy, Deviantart, Livejournal, and Plurk. I used to be huge on Digg and Fark, then Reddit but it got boring.
