Hacki's Ultima Page is the only Ultima website dedicated to nitpicking the Ultima series, i.e. discovering every little fault in the games. This site is an extensive archive of Ultima nitpicks submitted by many different people; anyone can submit a nitpick, though there are a few simple rules to prevent it from getting boring (no nitpicking of bugs, for example).
Hacki's Ultima Page started off by aggressively nitpicking Ultima 9, to prove what a poor game it is. For fun, the nitpicking tradition was eventually extended to all the other Ultimas.
This is the home of the Ultima 6 Nitpicker's Delight Patch among other things.
