I definitely think that questions about web apps are off-topic on Super User.

But I agree with you that those web apps are getting more and more important.

Maybe it's time to extend the trilogy with yet another Q&A site specifically aimed at web apps? That way those off-topic question which are already on Super User could be migrated in stead of just closed (and maybe deleted in the future). I think this would really be the best option as a lot of those questions and answers have actual value!

OTOH, if Jeff and Joel don't want to consider that, there's nobody stopping you (or anybody else) to start your own wep app centric Q&A site using the StackExchange platform.

I just checked the List of StackExchange Sites, and there doesn't seem to be something like that yet. I think there is potential there.
