Hi Michael, as a tech person, I'm not articulate enough to sell my ideas (and I have lots of them :)) or explain problems that need to be solved. Does YC sees that articulate founders (speech & presentation/looks) is a pre-requisite? Looking back at recent YC allumni, there have been 'easy' problems solutions (eg, tea bot, uber condom, smart mattress etc). I have a feeling that it was not easy for Mark Z to explain what Facebook all about. I understand that founders need to be able to sell ideas to VC. How can YC help companies with not-so-articulate founders? Thank you.
