Check out aWiseguy's profile page. He's embedded a video in which he discusses RIA, partisanship, and some ideas for a weblist. I think it's pretty cool how he uses this new medium to communicate with his readers.
How did he do it? He shot a video of himself, uploaded it to YouTube, copied the embed code, and pasted it into his RateItAll profile page.
Let me know if you see other folks doing cool things like this with their profile page, and I'll mention them on the blog.
