A Weekly Feature?

I'm considering running a series of weekly features. I read a couple of blogs that do this, the posts on a specific day all follow a particular theme. It might be good fun, and provide a little inspiration if I were to do something broadly similar. I'm thinking of a few options, but if anyone wants to leave a suggestion in this post's comments all serious ideas are welcome.
