This is a fair question on the surface, but one thing that occurs to me — given the sheer number of similar-looking things people put out, people may not have the time to exhaustively compare their offering with others. You often only discover differentiation by diving deep into each framework/lib etc, and if you dive into every Twitter-amplified new framework/package then you would never have time build your own thing.

So I guess what is a builder to do? Probably focus on practical use cases, show adoption and let these speak for themselves?
