WSJ reports (via Paul) that the owner of Dictionary.com, Thesaurus.com and Reference.com domains just got sold to Answers.com for $100m.
The number is large enough to assure me that much analysis has gotten into it and that this is not purely speculative. It also makes me suspect that not enough players are doing that and it leaves the internet traffic market less efficient than it should be.
I wonder if securitization of domain name sets could be in the future.
