Just a head's up on a pretty cool site that I came across today: Command-Line-Fu
This is the place to record those command-line gems that you return to again and again. Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on and discussed - digg-esque voting is also encouraged so the best float to the top.
This site is still in alpha - so if you have a new feature suggestion or find a bug, please report it at Command-Line-Fu Uservoice
