anachronism

From today's headlines:
Socialite Anne Bass was one of two people injured during an armed break-in at her Litchfield County estate, state police said.

I had no idea the word "socialite" was still used. I could imagine it being used in a completely sarcastic sense but not as a sincere description of a person. And what shocks me most is that I live in a state where there are people who are apparently best described as "socialites".
