You do see the occasional hack name sold for a decent amount , but it is not the norm, i do think around some domain circles ca.rs would be considered a ripper
I have had worldne.ws for a few years now (forgotten website) that used to be page one for google "unusual news" search , have not looked for a while , i do see hack names at bido.com sometimes
They are fine names but only a minority will see any value ...........develop is the answer
