I didn't think this was good. Her basic definitions at the beginning (eg virality) was very poor. Either she doesn't have a clear understanding of these or just isn't that good at expressing herself (hopefully the latter). Her thinking is quite convoluted. Did anyone else think this?

In this interview, I particularly enjoyed hearing the descriptions of a network, marketplace, and platform; as well as the questions founders of each should be considering when building product and growing a user base. I haven't figured out how this effects the application I'm working on yet, but I think it should help me hone into some possibilities...and likely more questions. (e.g. Am I building a marketplace or a hybrid marketplace/network?)

Focusing on generating demand and retention of current users while growing is a key piece that I need to keep repeating to myself. Thank you for your insights Anu and thank you to Craig for doing these interviews with the YC partners.
