So I've been running a caption challenge blog for a couple of months or so, and got a few responses. I thought I'd announce it here so anyone who wants to can see the stuff that's been posted there. Feel free to respond to any of the challenges if you want.

I have a vague dream of signing on some other people who enjoy making caption challenges to co-own the blog, and maybe have a few different people making challenges so it's not just my ideas.
