META: What about Fridays?

I need some ideas for an ongoing series of posts for Fridays. Or Thursdays. I'll be doing Open Critique Days on one of the two starting next week again, when the hardwire internet at the new place is done, but that still leaves one of the two days without a "theme".

Any suggestions?

In the past, Hammerknight suggested RPG Day, where we would talk about anything related to role-playing games, and from time to time we do Friday Night Fights, and I've done "Why I Hate Rob Liefeld's Art". But now I'm out of ideas. Help!
