I tried Gliffy Online for the first time this morning to create a simple flowchart and I definitely will be
playing with using it for important work again. What I like about Gliffy:
– free basic account (you can purchase a premium version)
– easy-to-use (if you’ve had some experience using Word or Powerpoint drawing tools)
– web-based (so you can you use it from any computer connected to the Internet)
– social (you can collaborate on diagrams and share work with colleagues).
