Seesmic is fun, but is it useful for business?

A while ago, I stumbled upon a Twitter discussion between Realtors about using Seesmic. I had never used it before and was curious, so I signed up and tried it out. It was fun, and interesting, but I don't see how it might be useful for doing business. You can have it automatically update your Twitter thread everytime you post a video, so there may be some benefit there.

Has anyone had any experience with it? And how do you use it / like it?
