My motivation for this was seeing that people regularly pay freelancers on oDesk/elance hundreds of dollars for this kind of thing. Or perhaps they're paying way less than that, but they're waiting weeks just to get that first buggy 1.0 version deployed.
So I think there is real value here for someone who wants to get their basic webapp 1.0 version out as quickly as possible, and not have to pull their hair out over stupid things like signups, or Facebook integration.
I am in fact sitting on some Adsense ads for this, but first I wanted to get some basic feedback on whether I'm totally off-base or not with the idea. Thanks!
