- I Can Has Hotdog -- for loldogs
- Pundit Kitchen -- for lolpoliticians; or a place where you can "cook up pictures for your political blog"
- GraphJam -- for, well, lolgraphs; or, more accurately, "Pop culture for people in cubicles"
They also maintain Speak LOLspeak, which is the "The Definitive Lolcats Glossary" and an invaluable resource.
And then there are three other funny, but more specialized lol-related sites:
- The Lolcat Bible Translation Project -- Teh Holiez Bibul
- LOLCODE -- Programming the LOL way
- Loltheist -- Blasphemy is Teh Funneh
There are, of course, many, many more of these sites but those three are, in my opinion, the funniest of the lot.
