How do you keep internet bookmarks?

For netizens who can't live without internet for at most 24 hours and google everything online, of which most of us are, it is always painful to organize the ever-growing bookmarks of sites that we want to keep, or it will be more painful and time-wasting to scroll down long array of links.

This becomes more troublesome when you are going to change default browser or computer, where it involves export and import of bookmarks, sometimes it may just turn messy and you would have to drag and drag and drag again...

I had wondered if I could classifying these links in a web blog but then it seems stupid if that blog couldn't be accessed when I need to. Then I thought of using a separate document to keep these links and upload the document to internet or store in my pen drive.

So, after a while, I start using Excel spreadsheet to help me keep the huge list instead. Though it is less convenient than using browser's bookmarks, it is more customized, effective and accessible in any browser or computer, as long as I am connected. [Do I still need internet bookmarks if I am not connected? :)]
