It will cause you to spin further into the beer obsession period. It's a social networking application/website for beer heads. You check in to the beers you drink and it keeps track of them and recommends new beers. Then it rewards you for your steps toward alcoholism by giving you "badges".
Personally when I started brewing I ended up spending the same amount on beer as before. I still buy a lot of beer, but I buy bottles that cost as much as twelve packs did before. :
