Try workflowy.com.[1] It's a minimalistic bullet-point, hypertext note taking service; I think it has potential, and quite good usability.

I predict of of these lots services that are popping out everywhere will eventually achieve just the right features/simplicity balance, becoming a killer app through network effects a la Facebook and wiping out all the competition. Evernote is close, but not quite there.
