Nifty Gliffy

Web 2.0 tools continue on their march to world domination. Latest to come to my attention (thanks, ResearchBuzz) is Gliffy, a diagramming program that operates within your browser. It can do what most commercial programs do (Giffy is free now but will likely charge in the near future), and it allows you to export your diagrams or share them on the web in various ways. Particularly useful is the ability to export in svg (scalable vector graphics) format, which permits the resizing of the image without loss of quality.
