I like the Untapped app. It focuses mind on pursuing a variety of beers and not stopping the exploration. I had it for a while but just starting to use it. In short time I begin to actively pursue variety in beer just because the tasting and drinking serves as a piece in a game board. I wish they had a good one for wine too. Must be casual as Foursquare and Untapped. It forces discovery AND can be great for merchants. These apps are very primitive but look cool. I guess someday they improve. Not?
