I'm a marketer and I read HN daily. I don't think this is as insular a community as it once was.
If you are now working in Starbucks, you aren't likely to read HN _because you are fed up with this stuff_. Not because you can't.
Most people outside of the startup scene, including myself, especially those over 35, are only in this for the money. That doesn't mean we can't find both personal and professional success.
