I recently became a twitter user, and I immediately got addicted. I really have the sensation that twitter is extremely powerful, even if I still don’t exactly know how. So, while I think a little more about what can I do with it (as tool/platform for my job, I mean), here some fun things you can do with the 140 chars of a tweet:

• Sell stuff (the service is free!) in a auction-based or fixed price way. Who needs eBay anymore?
• Serve an injunction.
• Control your lights or even fully automate your home. Amazing.
• Remotely monitor a server: here and here.
• Control a Mac.
• Get a taxi? Why not…
• Play chess (even against the whole community, cool!)
• Notify the entire planet that the view is beautiful from the space.
• Publish a newspaper, now we know it’s possible.
• Hold a worldwide press conference.

140 chars…. not too bad eh?
