I'm mostly editing for grammar, clarity, and oversight/bias at this point. I'm interested in presenting things as neutrally as possible, a difficult part of which is incorporating relevant controversial views in proper context.
I don't know that much about the way oversight works on wikipedia, but it is such an influential source of information at this point that I think it has great potential to be manipulated by powerful interested parties. Once beliefs become established within a culture, they carry the power of the status quo. So we must guard against assuming the mainstream viewpoint is correct, while carrying information about relevant popular opinions.
Recently, I've been investigating corporate and or government corruption issues (medical study oversight, military contracting, fracking) and conspiracy theories about JFK, MLK assassinations, "the Fed" (still not sure what to make of all this), 9/11.
