roulette.org.uk was bought (i would imagine) as a great seo domain for, wait for it, roulette, the gambling game and may easily pay for itself in first year with just affiliate links and developed imho, so a good buy
the cam roulette thing is for a porn site and no doubt they too will make money back. it was an insane purchase i thought at first and bogus, but then saw developed out really professionally almost instantly, based on this chat roulette craze
so i guess you never know
thats the mad thing about this business. when i first saw chatroulette.com sold for $1500 i thought was a nuts buy, then when went to auction and sold for xxx,xxx , i called bs too, at first
anyway, i think roulette.org.uk is a solid buy for what is not a lot of cash
nb: to Americar, just reread your post and i see now what you mean, where you think was sold very cheaply? if so, agreed, i know .org.uk is not sexy, but it can rank as good as anything on google, and thats the key
