Gliffy is a pre-launch startup, which makes a program for collaborative drawing. I signed up for the beta a few weeks ago, and just got invited today.
While I haven’t tried out the collaboration feature, I am pretty impressed by the program overall. First, I was surprised that it actually worked, until I found out it was written in Flash (after which the only surprise was that copy and pasting text worked). I am also impressed by the use of screen real estate. All of the features needed to do a drawing are given space, and it is much less cluttered than Microsoft Office (don’t even get me started on Office 2007 or Windows Vista). Another thing that impresses me is the versioning system built into it.
I think with the new crop of office applications, including those from 37 Signals, and a web app to tie them together that hasn’t been invented yet, we could start to see a shift from desktop office applications to the web in half a decade or so.
