YubNub - Command Line for Web Browsing

If you're a command line freak like I am (or like Scott is), maybe, just maybe, this YubNub site is for you. It's essentially a "command line" gadget for web browsing, that help create and run short commands instead of clicking browser buttons.
Interesting concept.
