Er, ok, I formed my opinion as to the relative liability cost as the executive in charge of DMCA of a search engine that raised $63mm. I dislike appeals to authority on HN as much as the next person, but you sure seem confident at knowing something about small search engines that only a small number of people actually have experience with.

And if you've never gotten a DMCA takedown from Perfect 10, you probably don't understand the true terror of the DMCA process.
