Two hours ago I encountered a post on rec.puzzles asking why the type of puzzle known as a ‘ditloid’ is so named. I'd never heard the name before, but it turned out to have a brief Wikipedia entry which included an etymology, so I posted a link in response.

Just now, I went back to look at the Wikipedia page again, and found that it had more than doubled in size. Checking the revision history confirms that someone has filled it out significantly within the past two hours.

It seems reasonably likely that the timing isn't coincidence, which would imply that whoever edited it probably had it drawn to their attention by my post on rec.puzzles. That's just a little scary, somehow.
