maths alert
cheers! behind the scenes, the randomness is the Mersenne Twister (a 1997 hit by that Japanese duo, Matsumoto and Nishimura) shuffling all items in the hit-list, and then selecting 20 off the top. MT provides a nice pseudo-random distribution and also has a website in the best old-Web tradition.
(edit: i didn't intend to lurk so long)
