>User Experience. Developer Experience. Community.

But that's what I'm saying. If you find some solution to a problem that's making decent money, some guy with big capital will just come in and "fast follow" you with better user experience and advertise the shit out of it until they have a better or at least more active community. Like suppose this guy's admissions scheduling app actually started making money. Why wouldn't some big player like Pearson just come in and roll him? They can easily hire a bunch of guys to copy what he's doing and then leverage their existing relationships with the education industry to lock him out.
