Mostly use Facebook and occasionally Twitter. I find the interface on fb far more easy and intuitive. Maybe I"m just old, but trying to navigate and have a convo on twitter is just confusing with all the hashtag nonsense. Instagram seems to be mostly random pics as far as I can tell. Snapchat seems to me more geared towards kids and something my daughter uses to talk to her friends. IMHO of course and your results might differ.
