What will they think of next? This could be pretty cool!  Tweet-A-Beer will let you buy a friend a beer, no matter where they are. The app links up your Twitter and PayPal accounts to a service called Chirpify, allowing you to send a cool $5 to anyone on Twitter, based on their @ handle.

The website says:

Tweet-a-Beer connects your Twitter and PayPal accounts together to ensure that distance, agoraphobia, and gang rivalries no longer prevent you from sharing a pint. Please tweet responsibly.

Once you sign up,

choose the @recipient (on Twitter), send them a beer ($5), and add a reason, meeting place, or requests for the juke box. Once submitted, the recipient will receive a tweet mention from you with a link leading them to details on how to claim the beer money.

Cool idea.  Now, if only there was a way to tweet a real beer!
