Opening Up the WebOS

I realise I am a little late to this, but I have to say that YubNub really is the bee's knees:

YubNub is a command-line for the web. After setting it up on your browser, you simply type "gim porsche 911" to do a Google Image Search for pictures of Porsche 911 sports cars. Type "random 49" to return random numbers between 1 and 49, courtesy of random.org. And best of all, you can make a new command by giving YubNub an appropriate URL.

The most important bit is the last: it allows this command-line to be extended in any way; moreover, there is a wonderfully Darwinian element to which of these extensions "survives", in the sense of being used.

I can't help feeling that something really big will come out of this one day. Web 3.0? Web 4.0? I don't mind waiting....
