Judging by your blog entry your resources were extremely strained; are you saying if YCombinator wouldn't have accepted you that you wouldn't have pursued any other accelerators even if it would have helped or possibly saved your business if it got bad enough? Seems like a short-sighted statement in my opinion.
What if you want to start another company in 3 years, don't get accepted to YCombinator and decide to apply elsewhere? They may read this and use it as a deciding factor.
