Have you tried Quicksilver? It's a much more efficient way to open folders then using term + open.

I think you misunderstand me. I use the terminal constantly anyway, so when I do want to view a directory in the Finder (which is relatively uncommon), I just use 'open' to do it.

Granted, I'm not much of a Quicksilver pro, I mostly just use it to launch apps, but I have my doubts that I'll ever use it for opening folders unless it's one of the few commonly named home folders (Downloads, Documents, Sites, etc).

edit:

Though if you know some special tips or tricks to open folders with QS with tab-complete to get the right path and all that, I wouldn't mind knowing about them.
