There's a snazzy tool that everyone but me seems to use: del.icio.us. It allows you to bookmark pages, store them on a remote server, pull them up from another browser (thus making your office more portable) and share them with others. By seeing what others link to, you find new resources. That's neat.
del.icio.us recently was bought by Yahoo!, so I'm also giving the very similiar de.lirio.us a spin.
When I populate my account with my favorites, I'll link it from the sidebar.

In the mean time, I have found a blog whose links so closely match my own interests that I found it eerie.
