Google docs looks like the kind of product a team of students could build as a summer project. It's missing all kinds of fairly basic features (have fun adding a text box or arrow between two things on the document for example.) Yet somehow it's still the best thing out there for shared documents. I suspect it is winning by network effect and lack-of-business-model meaning nobody else can compete with 'free'.
