"Awesome Diagram Software"
Amazing Layout routines that mean you can worry about the content not how it looks as yEd will make it look great. Good list of symbols and diagram types. Loving BPMN symbols. Works on most platforms. Free and has the backing of a company.
Nothing. If I had to be picky I'd say it's not easy to get data into in.
This software blows away every other diagram program I've used paid or not. If you ever have to do a process flows, network diagrams, family trees or organisation charts. this is the program for you.
