This is sensible and good for the entrepreneur. If its good for the entrepreneur, its good for the prospective accelerator, its good for the prospective investors and so on and so forth. The virtuous cycle is for real. The issue is the not-so-famous accelerators bear the brunt because almost all applicants are awaiting response from YC and not the other way around. If the conclusion of this is you give you short-term exploding offer, the accelerators have got it all wrong. Instead, the right perspective is that they need to make their value prop as strong as a YC. Glass half-full/half-empty, remember?
