Yubnub - quick searches and more 'quicklinks' style

Yubnub rocks. It gives you a search box in Firefox that lives to the right of the URL bar. Here is some example usage:

Google yubnub: g yubnub
Google maps search: gm bicycle stores boston
Wikipedia search: wp monkey

This is only scratching the surface, there are hundreds of different shortcuts.

Update:

I stopped using yubnub because I didn't like the idea that one guy knew my IP address and everything I ever search for. This is worse than google knowing everything I search for because by its nature it ties everything together: flickr, delicious, wikipedia, mysql.com etc.
