I am a fan of what the guys at http://www.swig.co/ and http://www.drinkeasy.co/ are doing (disclaimer: I know the founders).

Swig is a social application that enables you to discover new brews that you might like (based off of you and your friend's preferences); sort of like Pandora for your palette.

Drinkeasy is an extension of Swig and enables you to order those drinks.
