Writeboard is yet another nifty 37 Signals web tool. It’s a web-page/whiteboard app that lets any number of people edit a page at the same time, or in other words: a wiki without the suck.

It seems that the killer traits of good web applications are:

• Simple as pie
• Do one thing well
• Smaller is better
• Connect to other things easily
• Bring people (or ideas) together
• Free or free, either will work
