This question that I asked several months ago appears to have been recently deleted:
https://superuser.com/questions/4143/what-interesting-types-of-things-can-dropbox-be-used-for
It had a large number of views, responses, and votes, earning me the Favorite Question, Good Question, Nice Question, Notable Question, and Popular Question badges.
I do realize that this wasn't technically a question attempting to solve a particular problem, and really shouldn't have been asked at all, but deleting significant amounts of (seemingly) quality content seems a bit harsh. Questions above a certain threshold of activity should probably be left alone, or just closed to archive the content.
