The irony of this being fully hosted on GitHub should not be lost. A toaster is sufficient to host a mostly static site, a VPS would be far more than sufficient.
GitHub is free, a VPS isn't.
I absolutely agree with the concept, but people have to be ready to do their own work rather than delegating it to other parties. Consolidation has happened because these massive conglomerates absorb operational complexity on the cheap, and that's attractive. Moving away from them means we take on the responsibility of doing it ourselves.
