I make an effort to follow the policies and guidelines, by copy editing in a neutral tone, reading reliable sources, and summarizing them. I find that a clear focus on summarizing reliable sources helps me leave beliefs and opinions out of my editing. I try always to assume good faith and have yet to be disappointed by the results of doing so.
I gravitate toward articles about social networking sites and social media out of interest in understanding them better (perhaps because I don't use these platforms myself), but mostly I try to help out wherever I can.
