Thanks everyone! Halving the bounty after this point due to huge response.

I don't need a bounty on this.

Check through them though, some of the ones posted repeat ones on that first link I posted. That linked page really has a lot of the working dot-bit sites that are more than a placeholder. Also, many many of the ones listed (especially most of those listed on dot-bit.me) are simply placeholder one page sites, which isn't what you're looking for, right? you're looking for developed websites, or at least mirrors of .ICANN developed websites. Correct?

http://dotbit.me/
is a continulally auto-updated list of (as far as I can tell) every dot-bit site that resolves to anything. There about 400 of them. Once you start looking at the sites (with the proxy, or with MeowBit), you'll find most of them are just placeholder pages. Many domains even have the same placeholder.
