Which module should I write about next?

I had some great feedback about the PyMOTW series from several of you at PyCon this weekend. Unfortunately, when I put you on the spot, no one had suggestions for what to write about next. I’ve been going through the library more or less randomly, and in the absence of a better idea I can continue with that plan. On the other hand, if there’s a topic that you would really like more details on, let me know and I’ll try to bump it up in the queue. My regular work schedule is pretty slammed right now, so smaller (or simpler) modules will be given higher priority than anything like re or socket, both of which have entire books written about them.

So, speak up and let me know what to write about next week.
