This is a bit cynical but not wrong. Twice now I have ended up in conversations about how I would "re do" search if I could that talked about whether or not you could sell people the value. When I was at Blekko we had a tremendously enthusiastic librarian user base who loved being able to curate the sites searched. But product was so focused on ads, nobody seriously considered a paid service. (Libraries subscribe to all kinds of services for example) Most users however would not even provide an email address which would allow them to elide spammy sites from their searches. It was an interesting thing to observe.
