How often do you find yourself saying, “Man, I owe you a beer”? Probably pretty often, right? If this sounds like you, you may want to enlist the help of Foamee, a Twitter-based “IOU” beer tracking service. That sounds way more complicated than it is; in fact, Foamee is a breeze to use. If you’re already a Twitter user, you can track Foamee via their username, “ioubeer”. When you owe someone a beer, send a message to Foamee in the format “@ioubeer @twitterscreenname “reason beer is owed”. Your IOU will then show up on the Foamee homepage for all to see. You can check who owes YOU a beer by visiting the “People” page on the Foamee site. When you’ve paid back the beer that you owe, the recipient can post a “Redeemed” banner next to your IOU post so everyone knows you’re a man or woman of your word.
