SeenBefore: A search engine for what you have seen before
Obvious point to raise: the reason people regularly delete their browser history is because they watch porn without turning on private browsing. How do you propose to deal with this?You'd need to provide at least the ability to selectively delete portions of the history. But you can selectively delete portions of your browser history too, and people don't - because it would be too easy to miss something. Instead, they just nuke the whole thing. How is your tool different?
