What's next?

Lots of articles about weblogs recently. Mainstream media outlets all have weblogs. Weblogs feel like they're jumping the shark. So what's next?

I feel like it's probably not podcasts, since it takes so much time to listen to someone talk about stuff, and it's a lot easier to read a weblog at work than listen to a podcast, and there's not that much you can do with a podcast that you can't do with a weblog (play music, have real-time debates, probably more cool stuff I'm not thinking of, but it's not making me excited about them, yet). So I feel like there's some other new form of communication out there that I just don't know about yet.

If you know what I don't know, and there's something out there I should know about, I want to know.
