If you need to create quick and easy diagrams but can’t justify a full priced tool like SmartDraw or Visio then you’re in luck. Dia is an open source diagramming tool that will make a welcome addition to your diagramming toolkit.
If you think of Gliffy as Visio delivered as a web based app you’d be about right, just like Google Docs. Google, if you’ve got a spare few million bucks (and we all know you do), will you just buy Gliffy? And then integrate it into Google Docs. This stuff is way too good to waste behind a paid-for monetisation strategy.
