Maybe. It's partly just perception I'm sure, but I was late-teens/early-20s during Slashdot's heyday, and generally got the impression most of the commenters were older than me. I am thirtysomething now and have the impression most of the commenters are younger. So I don't know if it's literally the same audience -- obviously some of it is, as I'm here, but overall how many of the HN posters were also Slashdot posters in 1999 or 2000?
