You know, someone needs to make an Iron Chef styled reality TV show where teams of web developers are each handed a random recently-expired domain name and challenged to make a viable service that fits that domain.
You joke, but I know people who hunt to acquire domain names first, and then come up with business ideas based on them. Putting it bluntly, I feel that this is an astoundingly misguided way to operate business ventures, and, so far, the market seems to agree.
