And after the initial controversy surrounding Quinn, the focus was re-aimed on gaming news sites after their suspicious near-simultaneous "Gamers are Dead" articles. Mailing lists were uncovered among other things (Google GameJournoPros), and people then started boycotts against these sites and emailed advertisers asking them to not sponsor their sites. Gawker's lost seven figures' worth of revenue so far, I believe.
One of the biggest problems with GamerGate is Twitter, where spontaneity, trolls, and misinformation reign supreme. A troll co-opting a hashtag and claiming that it wants to subjugate all women is much more juicy, much more noticeable, and riles people up more than something such as a level-headed multi-paragraph post on Reddit or some other site about how game developers shouldn't have to
I used to be much more emotionally invested in GamerGate but I backed off when I realized I was dwelling on it too much.
YouTube (among others) is going to eat dedicated gaming news sites alive if they haven't already, anyway, and YouTubers are even more beholden to their followers than game news sites are to theirs. If a YouTuber does something dishonest and people find out, the blowback will be significant and nigh-instantaneous. Much more accountability than a site like Kotaku that has (or used to have) mounds of advertisers to back it up.
