edit: Probably too much time spent on hn
Maybe 'Broker News' or 'Teller News'?
I actually like the idea of this site. I spent a few years consulting in financial services and always found the world fascinating. I could see myself browsing it on a regular basis.
As a member of your target audience, I'd suggest focusing on the discussion side since that's where you likely to be able to add value. Finance professionals already have content professionally curated and ranked by the various paid news services - Reuters, Bloomberg TOP, READ (ranked by views) etc., but there is no discussion there.
And thats a big shame, because I was recently lamenting the lack of Slashdot/reddit/HN for the finance industry.
Kinda like how you forget your wife's phone number.. I know I should know it but I always click her name in the address book :)
Plus broad audience, I have only met a few bankers that are not bored with their jobs...
Has links to some nice articles btw
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."
EDIT: I am currently considering changing the domain (and the title)
BoredBanker is an excellent name - memorable, amusing & not overly long. There's already enough dry, grey, "serious" content associated with this industry - having an offbeat and slightly subversive name will be part of your appeal.
People who tell you they won't use the site because of the name are being disingenuous - if the quality of news & discussion is good enough they'll come.
