For me it's a good beer to bring to a house party of people I don't really know. I don't want to walk into a house bringing nothing and I don't want to bring a 12 of some weird import/domestic beer that no one else will try or like.
It's the same reason I would bring a Riesling or a Merlot over to a dinner party. It's a safe bet and someone will drink it.
I don't know, I always see that as the perfect opportunity to turn people on to craft beer. Nothing like showing up at a party with a good Belgian White beer, telling people it is similar to Blue Moon, and watching their heads explode.
