In affiliation with the efforts here I present evaluation of ALL Internet communities that have a Freenode IRC presence:
Here's a list of domains referenced in the topics in at least one channel on freenode IRC network.

Note, you may use IRC client to connect to freenode irc network and search for the above urls to find the channels which they came from, otherwise most of them are pointless, or worthless other than to the tinyesque communities or founders behind the websites. Regardless, they are listed for sake of completeness.
I gave up on this, btw. It's not so important or useful as the other thread
