Great article and it points out an issue I've seen with a few startups. It's no one else's job to understand what you're building. Even if you hand me an application saying what you built I still want to hear you explain it. I shouldn't have to work to understand your product. The fact that YC was trying very hard to get you to explain what you were building and you continued to repeat yourself tells me you still don't know entirely what you're building, and to an investor that's a huge red flag.
