Gliffy. Think Visio as an online application. Web apps are the new black, aren’t they? This one is rather nice, I have to say, although when a couple of us tried out the collaborative function, it didn’t work at all, so it’s clearly a work in progress [maybe that’s why it’s called a Beta, duh? – Ed]. Interestingly enough the FAQ claims that this is just part of an upcoming ‘suite’ of online programs, which definitely could be interesting. Anyway it’s free for the moment and definitely worth a look, at least before Google buys it.
