Tweet-a-Beer has exploded onto the app scene. The "buy a buddy a beer" app allows you to paypal or transfer $5 to a friend for a cold pint. Say they had a long, crappy day or perhaps they just landed a fantastic new client, well, it sounds like it's time to celebrate with a little something to drink.
The ultra-popular app was developed by Portland creative agency, tenfour in conjunction Waggener Edstrom. Tenfour handled the creative direction, interaction design and web development on the project. The app is cool, but we love the fact that it acts as a model for future micro-payment systems between parties.
