I just want to echo how cool of a site this is. I'm actually not a designer at all(far from it, I do entirely backend work) but I've gone through most of your teardowns just because they're interesting to read and it's cool to learn about UX stuff like this.

The only comment I'd have is that I found the "zoom in on mouseover" to actually be really confusing at first, and I don't really get any utility from it. I suspect this is because I'm primarily interesting in what you have to say about the site, and not the zoomed-in details of a particular page.

Thanks for the site!
