Online Charts -v- Visio
Lovely Charts
I came across this from someone on Twitter. This has a fee of about $45 per year, but is free to make one diagram. I found it much easier to use than Microsoft Visio or other fat client software. This seems like a great idea because once your done with your diagram you don't have to email or post it somewhere. The site allows you to share the URL directly. Yet another cool online application. Give a whirl.
