Great idea, I have a couple of questions. Since YC Fellowship is intended for startups at the idea stage/prototype stage, is ApplyHN a catch all for businesses at the idea stage looking for feedback from the HN community? Can you do an ApplyHN twice? Presumably once you get feedback from your initial ApplyHN idea post, you might flesh it out more and have a stronger application the second time. If you're at the prototype stage normally you might do a ShowHN, should you create a separate post for an ApplyHN if you want to apply?
