Unfortunately GitHub seems to be pretty guilty of this too. Lost count of the number of times I've clicked a link in a blog post only to end up with a GitHub 404; I'm sure it is only going to get worse. Most annoying thing with that one is usually simply going to GitHub search and putting in the original 404'd repo name turns up the one I want. I'm sure having the 404 serve up a "did you mean" search result would solve the issue for the most part.
