Joost™

Joost™ is an online video streaming app which is totally awesome, in fact I'm watching "The Tick" as I type. It's available for free for both Macs and PCs. There are some commercials, but they're very few and far between.

Vienna

Vienna is a great open source RSS/Atom newsreader for the Mac OS X. It's the best reader I've used so far; a simple, user-friendly interface and very well organized.

VoodooPad

This weeks awesomeness pick is VoodooPad, a Macintosh app by Flying Meat. It's a great catch-all notepad app with lots of great features. It is available in three versions; lite, regular, and pro. I only have the lite version, which is free, but if you've got the cash, it's worth it.

EDIT: I just broke down and bought the full version of VoodooPad and it is totally worth it.
