The great thing about being a geek is that you can do stuff without the nagging question "Why?". To a geek, the questions "Why have you made the toaster run a web server?", "Why have you built a teddy that speaks Twitter?" and "Why am I not surprised you're single?" don't ever factor into any decision making. Which is why someone has made a beer pouring robot that's powered by Twitter-alike microblogging service Pownce.
