Is it just me, or do real entrepreneurs need to be less excited about this YC interview thingy. If you care so much for third party approval from PG and folks (not that they are not nice/smart ppl) but then just go to a B-school dude and get that nice degree which will surrogate for your competencies in the real world. BillG didnt need no YC, neither did Google guys and neither did the ipod god - infact even PG didnt…
We were very lucky to have Julian, and we would have been even better off with YC, which is a superset. In addition to all the above, you get other startups as colleagues, and startup-specific advice.
