I have a couple of friends who own various single word or three letter domain names. They universally say that companies attempting to buy their domains tend offer seriously not life changing amounts of money and often resort to threats when rejected.
Consider what if Land o Lakes owned milk.com and you demanded they sell it to you for $5k? Bwhahaahahaha!
I don't know how high the offers can go these days. But then again, we're not exactly in the dot-com bubble anymore. In 2001 I bet it could have attracted life changing amounts.
Yeah sometimes people spend inane amounts of money for things. If someone was willing to pay $7.5 million for milk.com it'd be theirs. But no ones offered even 0.1% of that. So the market says milk.com really isn't worth very much. And the owner of milk.com and my other two friends that own single word domains are using them for their personal websites not squatting on them.
