Are you applying with other cofounders? Deciding not to go will affect them, too. My point is that if you pull your name will not be listed. And your cofounders will probably not be listed either, as YC will likely pull the invite if a cofounder chooses not to accept. I would make sure your cofounders know you are undecided. And what is the thing about YC posting acceptances? I was not aware they do it.
