There are many social networks out there, and, let's be honest, most of them are pretty awful. I mean, really, what has Facebook done for you lately? Preciously little, or so I assume.
A trend among newer social networks is to be more specialized in certain interests, and this is probably why we like Untappd. Here's a social network where you simply post what beer you're currently drinking. You can add a score, location, and a comment to the "check in", which is a good way to keep track of what you like and what you dislike.
This is, of course, a social service, so you can add friends to learn what they're drinking and even comment on it. That's a good way to discover new libations, particularly when you start finding Better Tasters who you don't know personally, but who you share tastes in beer with.
In that sense we'd say Untappd is edutainment! (We're bringing the word back.)
Check out Untappd if only to become a social-ish drinker. It's available for iOS and Android devices, and also on the web.
