To me (a UK citizen) this is like the government tracking the title and author of every book I read, "but don't worry, not the contents or page numbers you looked at". The idea this is any meaningful barrier to finding out what you're really up to is ridiculous. Phone metadata is one thing - and still highly revealing - but much of the web is public! It's enough to make me think twice about where I browse, wondering "if I ever got challenged over it, how will it look that I browsed to this site?". That seems pretty harmful to the web - possibly even in an economically measurable way?
