Ha - that'll make it easier to refer folks to the website. I hope to never need to utter - "Oh you should checkout Hacker News, go to news dot why combinator dot com, I think it will be right up your alley."
The other reason is that I'd prefer not to navigate the conversation toward "why I'm on a website with 'Hacker' in the name." That's a separate issue for which I am ill-equipped to discuss, given the mainstream connotation.
