I have been using Gliffy for a few weeks. As a free web app it is excellent. The problem comes when you loose your password (no accounting for stupidity) and you loose everything that have done. This is slightly mitigated by the fact that the free account only lets you create 5 public diagrams.
I have not really taken to it because I have a non-free installed app on my mac book pro called Omni Graffle which really does the business when it comes to diagramming and it doesn’t lose my stuff AND it is so much more feature rich than Gliffy that I cannot begin to describe. However it does NOT do collaboration and it is expensive, especially compared to ‘free’.
I have also been experimenting with Google Docs and have set-up an academic group for everyone who has an email address for my school. I have high hopes for this but it does, of course, rely upon the internet connection available. In the very near future I see this and apps like it really replacing the expeinsive HDD based office apps which cost too much and are becoming over burdened with glossy features that distract the user from the real point i.e. creating content and completing work!
I have also used writeboard.com which, if anything, is a clean breath of fresh air c.f. MS Office apps as I just mentioned. It is clean and no-nonsense. Just get on with the writing and don’t worry too much about the 3-d glossy buttons with a shadowy reflection! It is also collaborative which will make it a tool to use in the classroom.
