Hipster?

On a non-beer related note, is reading, referencing, talking about, or having knowledge of McSweeney's a possible sign of being a hipster? I'm still trying to figure them out (hipsters, not McSweeney's. Although I'm slightly baffled by that, too). From some article or another: "The ideal McSweeney’s reader (or writer) lives in Brooklyn, wears interesting T-shirts, has a blog he works on in coffee shops, and knows it’s cool to oppose globalisation but uncool to go on too much about it." Is that a hipster?
