Grognor does a couple things. Few edits here and there. He'll never be a major TVTropes contributor, but he has probably read closer to all of the articles here than anyone should. Life has been ruined by TVTropes, though there was no life to ruin beforehand.
Mostly, he fixes grammar, removes Natter, and adds examples. He has obliterated many, many instances of "This Troper" in articles.
Hasn't edited TV Tropes seriously in years.
The Other Wiki has an article about him, found here
.
Used to contribute to Less Wrong but doesn't anymore.
Importantly, is on the Twitter.
Has a hub.
