A list of domains emitting [Terry Pratchett] clacks headers

GNU Terry Pratchett

In Terry Pratchett's Discworld series, the clacks are a series of semaphore towers loosely based on the concept of the telegraph. Invented by an artificer named Robert Dearheart, the towers could send messages "at the speed of light" using standardized codes. Three of these codes are of particular import:

    G: send the message on
    N: do not log the message
    U: turn the message around at the end of the line
       and send it back again

When Dearheart's son John died due to an accident while working on a clacks tower, Dearheart inserted John's name into the overhead of the clacks with a "GNU" in front of it as a way to memorialize his son forever (or for at least as long as the clacks are standing.)

Hmm, I wondered a while back if anyone was keeping track of these. It seems to be a manual list so far, so added my main server, as that's been transmitting the clacks overhead since he died. Can't wait for the crawler to go live and then we'll see how many people did add it, including any big name sites.
