I have to say that's surprising. I'm relatively new here, but I thought most people would get here through Paul Graham/YCombinator, which has more to do with business than programming.
personally I came here because I would randomly check paulgraham.com ever since his articles relating to lisp were being posted on slashdot. One day the YC link appeared which in turn had a link to hacker news. While I have gained an appreciation for start up culture(definitely the hacking approach to business) since then I still primarily hang around for articles on programming.
