Google has just released an online chat program, dubbed Google Talk, that has three noteworthy features:

• The program is tiny, the installer is only 900kb whereas most chat programs these days run 10mb or more. This means that even modem users could download it quickly.
• It has built in support for doing voice "calls" to other users, you just need a microphone.
• Its based on open standards so it can easily work with other chat programs, and in fact they even explain how to use many existing chat programs to work with their service!

Pretty darn cool if you ask me.
