Seesmic basically is a video chat service where you can post a little video and then have other users respond to your video. Are you a disqus user? well you can use it to leave video comments or if you use friendfeed it works great with that service and embeds your videos to your stream.

pretty kool and a fun little service to play around with. One note it is in alpha so there are still bugs and enhancements to be made.

here is my little intro video I made for the service
