Thanks King!
Traffic seems to be near 100% type-in, the old site disappeared loooooong ago, the traffic is significantly steady despite the lack of content, SE indexing is null/negligible, as in any regular parked page, so I don't think there is anyone looking for an old site. Inbound links are scarce and useless.
However, because of its intrinsic very popular, short dict-word, medical, social, characteristics, I feel that revenue-based appraisals won't make justice.
