I read more about ycombinator and read a few articles...Although I guess it's a balance..I am interested and I also realize I missed an investment cycle. So- this should be an interesting space to hopefully hear about those experiences of the people involved in going to your summer session.

I sent something to Paul Graham, who suggested I submit it to HN. To submit I had to sign up, so I did. I didn't know of HN's existence before that.

That's actually the other thing I'm curious about (What motivated people to register). But there was no way to fit it in the poll :)

I assume most people register when they have something to submit for the first time or read a comment they feel they need to respond to.
