I use an ever expanding text file, plus bookmarks. The textfile is #1 for me, and can live on various drives.

like physically ctrl-v-ing the links to a file? that is quite a mental muscle to build every time you find something interesting.

		It's a pretty simple script mapped to a hotkey. Press ctrl-xyz after copying a url and voila. Not much of an effort at all to maintain a stable bookmark file. I use txt over other formats because I'm unsophisticated. But it's no marathon.
