If you'd like to see the camera become considerably more useful, please vote for Flash support for it. Then it could be used for video chats with anyone who has a PC/Mac/anything with Flash support. And for video blogging/podcasting.

There are also many dedicated video broadcast/chat sites (Ustream.tv, Stickam, Blogtv.com, Operator11, Mogulus, Veodia, etc) and more coming online all the time.
