[WhoaDomain.com]

I know thee answer. Do you?

Many domainers peddling their domains praise the value of their domains bases on the fact that it does not have the number 4 or 0 or both. In the domains and yet some of the " big players" in China domain market own hundreds of .coms that contain the dreaded 0 and 4. Why is that? Because they know something we don't!

So when are 0 and 4 actually "lucky" or "okay"?
