Ask HN: What web archive projects need help, or need to be created?

I've got some time, plenty of space on a server, and the patience to track down files/posts/etc. and organize them into an archive, and then script that process. I actually quite enjoy it.

I'm having some trouble finding a good project to spend my time on, though - the only suggestions I've really gotten are things like "collect all the episodes of this copyrighted TV show". What's something that I can do that would help even a tiny subset of the internet?
