Someone should make that as an app or web site. I think it'd be interesting for more people to experience it, and something less reliant on having dice and checking tables would be more accessible.

I agree that it sounds like a great web app (I had the same thought) but I think you need to be careful not to be too hand-holdy. Half the game is the journaling of the situation, and if you too hand-holdy I think you lose a lot of the impetus to do the journaling. Or at least to do it well.

Still, I'm definitely considering it for this one, or something like it.

I think that even without the journaling, it could give some insight into social phobia, depression and malaise.

This sounds like a fun (albeit depressing...) weekend project.
