ooVoo is a neat program that allows you to talk face-to-face with others along with sending video messages. Of course you need a webcam to use this service, but what makes it a little different is that it claims to be able to give and recieve high-quality audio and video. The installation file is pretty small, but the installation itself could take up to 20MB. It’s in beta so don’t expect too much from it.
Groovid is yet another video sharing web service. The twist that this site takes is to allow you to showcase the best videos from all major video sharing sites. I think of it as a Digg for video sharing. There are plenty of submissions on the site, but not much voting going on.
