Following a is a list of cool stuff I didn't have time to write individual posts about.
MyOpenID - If you don't know what OpenID is, think of it this way, one sign in authentication process for every website that supports it. Drupal 6 has it, Yahoo has it, lots of places have it - learn more about OpenID and get your own.
Tagurself - enter a feed link or a url and it generates a tag cloud for you.
TeamViewer - excellent remote desktop sharing software - and its free!
Microsoft SharedView - remote connection - sharing applications - great for training people how to do things remotely.
SightSpeed is a great award winning provider of Internet video chat and voice calling for friends and family, and video conferencing solutions for businesses. It offers really great video and sound quality with the highest-quality, full-motion 30 frames per second video with clear audio and no annoying delay. You can even send video mail and there is also a low-rate worldwide phone calling.
