In emails Zuckerberg says he is too busy to work on the site
Sorry it’s taken a while for me to get back to you. I’m completely swamped with work this week. I have three programming projects and a final paper due by Monday, as well as a couple of problem sets due Friday. I’ll be available to discuss the site again starting Tuesday…I”m still a little skeptical that we have enough functionality in the site to really draw the attention and gain the critical mass necessary to get a site like this to run…Anyhow, we’ll talk about it once I get everything else done.
