Social Media Alternatives?

[sdelmonte]

So as some of you know, I have a Facebook account that I use very sparingly, and don't plan to start using it more.  And a Google Plus account that was never of much use and is about to go away.  So I wonder what people use that isn't FB and isn't DW.  i do have an Instagram account for work purposes, and not averse to adding anyone who one to my list, but I don't plan to post there much either.   Are there social media sites that you use that are not the big ones?  Should I be using them?
