If hackernews was called "bored programmer" I would be reminded I was bored every time I visited. From a marketing standpoint, sounding cool and compelling is a thousand times more important than being literal and accurate.
My first reactions to:
"Hacker News" = "Whoa, hackers! This is what hackers read!"
"Bored hacker" = "What kind of hacker is bored? I want to go where the cool up-to-date hackers are."
"Bored programmer" = "Man, fuck those guys."
Plus broad audience, I have only met a few bankers that are not bored with their jobs...
Has links to some nice articles btw
