Have you ever posted on The Friday Five?

I've been looking for other examples of what I call "question blogs" and finally managed to stumble onto a big one, The Friday Five. Have you ever answered their sets of questions?

I just answered my first set. Kind of cool! I was sure I wouldn't be the only one with this idea. But, does anybody know what the actual moniker is for these "question blogs"? So far I don't really know what the category is called, or how to easily find others. But I'll keep searching.
