We often think about that. We could hire assistants, so we didn't have to do everything ourselves. Or we could make YC work more peer-to-peer. Or we could build a robot that would walk around telling everyone "don't make users register," "delete half the text on your frontpage," "face the audience when you're presenting," etc, and I could just hang out in the next room with a book and a cup of tea.
However, I noticed that YC did not ask for my email address, so it was not a painful way of registering. Also, you can read the news without an account.
