Online drawing - one step closer to being completely cloud based

The only remaining desktop app regret I have as I sit in my browser writing this on my iMac is no longer being able to quickly and easily jump to Viso on Windows to draw out that diagram that could save a 1,000 words of descriptions, and let's face it drawing in Google Docs is still a bit lame.  This online drawing tool from Gliffy is helping me get over my loss.

Very cool. Thanks to Alexey for pointing me in this direction.
