Cincinnati Hipsters Unite!

I can't comment to much on this story, I was not there, but I have to quote this part:

"These organizations are recognizing that they have to build young audiences," said James Czar, manager of information systems with Enjoy the Arts/Start, an organization that promotes art among young people. "Their older member base is eventually not going to be there, so they need to repopulate it now."

I doubt Mr. Czar would call himself a hipster, but I find it interesting this gathering was considered one of "hipsters." I have a negative feeling for the word and I am still unsure if it can apply to anyone in Cincinnati. For the record the dictionary defines a hipster as "One who is exceptionally aware of or interested in the latest trends and tastes, especially a devotee of modern jazz." Now, m-w.com has a more historical feeling of a definition:

Pronunciation: 'hip-st&r
Function: noun
Etymology: 4hip
Date: circa 1941
: a person who is unusually aware of and interested in new and unconventional patterns (as in jazz or the use of stimulants)

The modern usage from urbandictionary.com is the one that gives me the negative vibe:

someone, usually a teenager or 20something, who adheres to a counterculture ranging from indy-rockers to neo-hippies to skaters. they tend to define themselves by the music they listen to, and the outlandish clothes they wear. hipsters are opposed to other countercultures like goths, metal-heads, and gangstas, and they also avoid preps, eurotrash, white trash, and jocks

question: why does he only listen to bands that are never played on the radio?
answer: he's a hipster

So who is a hipster out there?
