Of of them are junky domains, come on no originality I wouldn't ever use site with domains like that anyway 
Let's face it - mtgox wasn't good of a name either.
Mt Gox was not booked by MK. Jed booked it.
Karpeles bought that domain from someone else.
Wasn't it orginally a magic the gathering cards trading portal or something?
magic the gathering online exchange
Why did he buy that and not just create something else?
