Rather than responding to everyone's complaints about the site: I whipped this together in less than a day, I was mostly focused on content, no one at YC who usually makes beautiful designs was available to help, I can't program, I'm using Strikingly, this is version 1. I'm happy to get feedback, but please go easy on me. We will plan much further in advance next year and make it easy to scroll through ideas and look…
In regards to concept, I think it's great YC is promoting YC cos at every opportunity it gets. Sometimes it feels like an ad, but this time it does not. Perfectly timed "launch" of the site.
I think you've done a better job than most, in both content and design. I looked at the site a few hours ago, and was thinking of the team and the week of prep work that YC put into building this. Never could have believed it was made by a non-programmer in less than a single day until I read this.
For constructive feedback, would love if you borrow an idea from Apple's gift list. That is, categorize the products and services by topic or type. I.e. For the music lover, the hipster, painter, etc. would really go a long way once this list gets out of hand (which I suspect it will ;)
