yubnub

I recently find out about this new web app (http://www.yubnub.org), for executing commands on the web.

For example if you type the command
"gim ferrari"
it does automatically a Google Image search for Ferrari images. "gim" is the command for google images.

Another command is "wp" for retrieving articles in wikipedia. For example if you type
"wp Stanford University"
it will show the wikipedia article about Stanford University.

It is the command line of the web. check it out, and create your own command! You can put yubnub in your personalized Google homepage, or Yahoo widgets.
