I used to contribute quite a bit on the MyFonts.com WhatTheFont forum. Then one day someone called Tecnotronic showed up and started dominating the board. He probably makes about 90% of the posts now.
Just another anecdote to support the premise of the article.
Edit: The link said "outliers" not "insane" when I first saw it. I did NOT mean to imply that my example was someone insane, far from it.
