I ran across a few tips from a friend of mine for social media success in 2015. It's a good list for anytime, not just 2015, but if you're going to use social media, it's a good set of guidelines for you.
The big things I wanted to point out were that I do think it's important to pace yourself. It doesn't have to be as regular as a blog, but try to participate on some regular schedule. My posts go up and down, but I do try to regularly become a part of the interactions.
Please, please, watch what you say. This is an impression you leave and you want it to be a good one. Not too many black marbles.
Tim mentions that he purges negative influences. I try to be careful here. It's easy to surround yourself with "yes people" that echo what you think and believe. It can be about life, or about technology.
I do purge people that annoy me too much, but I also try to interact with, and follow/read people that I disagree with. It helps to keep perspective.
