How do you build and maintain your social media presence?
I think this question is answered differently, depending on who you are behind an account and what your goals are.
For me, my goal is to be seen as a leader, someone you can rely on to give you the information you need around topics like Reddit, Social Media, and Futurism.
For that goal, when it comes to building, I focus on vanity strategies, recognizing and positioning myself with target connections, in a fashion that makes them connect with me.
When it comes to maintaining, I like to have a lot of sources for information, which relate to my area of focus. So I use Reddit a lot, join all the social sites dev sections and beta testing programs, and follow a number of sources that are known to be thoughtful and quick with topics. This way as I am reading and digesting what I want to learn each day, I become an aggregator / curator, of what I think is important.
