Reddit has lots of niche content that is extremely valuable the one time you use it, and I'm sick of seeing sites with valuable user-generated content dying off because the incentives of the owning company are misaligned with their community. Would it be possible to just re-implement something like Reddit on top of IPFS? Ideally that knowledge should never be allowed to die off until truly no one cares about it.
