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.
I checked he still has it.
