I agree, we do something fun in MLPforums.com like forum games, thread, dicussion and facebook... feedback, likes, picture, and personal stuff which isn't very much of fun but a chore.
Facebook never appealed to me. The only good reason I have for keeping my account there is to maintain Wii U Go's page. Forums feel less spontaneous, as they're all about having great discussions rather than dumping your life onto the Internet.
