Share 'Exploring people's sites'

I read with interest other blogger's sites and I find Helene's Library Bytes has a lot of imput from many people. Yes, Helene, I too have bits of info on envelopes, p slips, post it notes and 5 x 7 cards. My question-how do you begin to organize, keep track of favorite websites? and Oh-yes-the passwords. I love finding new sites and am grateful for other bloggers imput. Thanks for sharing!
