I use twitter for abusing Greenies and following horse race and sports industry people, but its also good for following beer geeks, I don't use untapped, I just view what the beer geeks tweet on theirs. Not much of a point using it in a small country town with fukall beer selection.
i've never been able to get this app to work properly, always some kind of issue,. I use "now tapped" not social but lists the beers on tap of venues i frequent. Heaps more venues added lately
