Agree with the majority of negative comments here. I think this is also a noisy signal for a couple other reasons. If the random topic is in some group's area of expertise, they're going to destroy the demo even if they are not the most fit. If it's wildly outside of a team's interest, say if they are great 3D rendering C++ guys doing a game and the project is a web app, then they could look worse than they are. It also irritates those of us who spend our whole day working on projects we don't have any special interest in. Finally, most web apps are simple CRUD apps with minor analytics and these are relatively easy to push out - that gives no information on scalability skills or marketing ideas or anything, really.
