I don't even now how anyone keeps track of them and finds the ones they want. And how can you possibly do that quicker than just going to the page afresh.

Part of working on a project for me is assembling links to important pages. It may be days, weeks or months later that I want to come back and there are the links. And of course, anything generically or regularly useful is just a bookmark as you say.

It really seems like people keep tabs open just to keep a list of useful pages. There are much easier and more effective ways to do that.
