>My motivation for making this was that I felt like there's hardly any resource for cool Web 1.0/2.0 esque websites that you can comfortably browse from a non-Firefox/Chrome browser.

You might already know about them, but here are 2 such resources:
http://wiby.me/
http://oldavista.com/

However, wiby is a search engine rather than a directory, and Old'aVista doesn't allow for new sites to be submitted, so I think your idea would fill that gap nicely
