I don't really care about it myself, and if it was confined to gamer forums or whatever, I wouldn't care one way or another. However it keeps popping up in mainstream articles I read that have nothing to do with gaming or gaming culture. I like to try to understand what writers are referencing, in the same way that if I see a word in an article I'd never heard of before, and can't infer its meaning, I try to look it up.
The Gamergate thing really is a "first world problem" and a lot of these people should back away from their computers, go outside and look at the trees and the sky, and thank God that they have a roof over their heads and food to eat everyday. I was actually surprised Adam Baldwin immersed himself in it. If it were me, I would have coined "Gamergate", then driven on and let them all drive themselves crazy with their microagressions.
Again, my only interest was learning what it actually means, since it has entered the mainstream and is referenced to things that have nothing to do with gaming.
