true jeff. my personal experience has been:
2 sales happened for .net for me recently this year related to t20 when
a) for 1st sale, i had .org as well and was also on sale on sedo but the seller did not made offer
b) for 2nd sale, i got offer on .net and low ball offer on .org
surprisingly, i get better pay for few .org then other ext websites...
sometimes, the matrix involved in earnings go beyond then explaining it !
