The evolution of shrinking blogs

The posting of short status messages on services like Twitter is often called "micro-blogging." The messages are limited to 140 characters. In a ridiculous development I have seen a service called Adocu in which you can post only one word, and the website calls it "nano-blogging." If this is the trend, then I propose the next step to be "pico-blogging" in which you can only post a three-character code to communicate your status. After that there will be "femto-blogging" in which you can only post a single character. The logical conclusion will be "atto-blogging" in which you only set a flag, a one or a zero (on or off, yes or no). I don't see how we can miniaturize any further. Micro-blogging is wacky enough already.
