what is the sad thing is that this people give a lot of money for a domain name and for the website and if they think they do that the succes is guaranted! invest 150.000$ in a marketing campaign for a modest domain name and see the results!
On the other hand, I have heard and seen so many twisted and wrong things about Sedo that sometimes I wonder if those six figures sales are just mounted tricks to bring attention. In fact I stopped using its services since long time ago just for that.
That would be a great way to get your name out there. Plus a great way to get the name of the site that sold for so much's name out there...
