Web Developer's Quiz: Your website needs to somehow know what are the other websites a user had already visited. How do you do it? How do you get the information from a browser history?
Under "import", a user usually uploads his OPML file (which I'd previously talked about), input some URLs, etc. In his attempt to make Tailrank's import applicable to more layman users, Kevin has a new "Auto Configure" button. Click on it, and a list of popular sites (that you have visited) are found and is ready for import. Damn, how did it know!
That said, I would've preferred if Tailrank actually gave me the option to uncheck some of them from my list (especially since removal of feeds isn't implemented yet)
