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. [[TVTropesWillRuinYourLife Life has been ruined by TVTropes]], though there was no life to ruin beforehand.
Mostly, he [[GrammarNazi fixes grammar]], removes {{Natter}}, and adds examples. He has obliterated many, many instances of "ThisTroper" in articles.
Hasn't edited TVTropes seriously in years.
TheOtherWiki has an article about him, found [[http://en.wikipedia.org/wiki/Jesus here]].
Used to contribute to LessWrong but doesn't anymore.
Importantly, is on the [[http://twitter.com/Grognor Twitter]].
Has a [[http://grognor.stacky.net hub]].
