I think there is a huge difference between a top commenter on HN trying to sell something and a non-top commenter doing the same after achieving a nominal karma rate. (I'm thinking specifically about what appears to be the recent spate of attempts by an company that rhymes with "muffer" to blog about all types of things in order to draw attention to their products.)
Anyone who spends considerable time on HN should be allowed to sell whatever they want that relates to their expertise within reason.
Perhaps the jealousy surrounding people who view "selling" and "business guys" as bad comes from people who don't have the makeup to take rejection that comes with selling. Lest anyone think there is no value to a "business guy" that it's all about technology.
