I just downloaded and registered, and I am having lots of fun with it. For those not familiar, it was described to me as "FaceBook for beer lovers." In summary, you can post/log anytime you are having a brew, including where you bought it and where you are drinking it. You toggle the beers from a truly huge database, and it even has the ability to log homebrews. (You can use generic homebrews by style, or you can put your own brews into the system) Basically, the app lets you keep up with everything that you try while simultaneously telling your beer-drinking buddies about the new stuff and whether it is any good. It also keeps a database of what beers have been flagged as being available at any given location. So, if you are looking for (for instance) Kilkenny Irish Red in your city, you can run a search and determine where that beer is available.
