Yahoo features their best sites (picked, apparently, on a weekly basis) from 2003. Of those I’m familiar with, the coolest are One Word, Bad Toon Rising and 365 Days Project. They also link to their best sites from 1996, roughly the mesolithic period of the Internet. I’m very impressed by how many of them are still up–more than 50%, from a quick check. Some look like they haven’t been updated since then.
