Listen, The Hyphen SiteThe Hyphen Site just drew attention to themselves and got a tiny bit more relevant for a while. The fact is, their business model is basically trying to get people to pay for an answer that MAY be there. It may work as long as they are listed on Google, etc., but it doesn't scale (to people who are smarter than that) and it is probably not going to last: if Google and other search engines decided to exclude The Hyphen Site, their revenues would drop like a stone.
Let them do their thing. Stack Overflow Overflow makes money in the following ways for now.
Ads for the relevant audience, which can fetch a premium for being targeted by keyword. The psychology is, Stack Overflow Overflow is helping you, so you are more inclined to click the ads -- especially if they fit with the message of helping you (by giving you the developers some tools). So I expect Stack Overflow Overflow ads to convert better than your average site.
Jobs site. Stack Overflow Overflow should really beef this up and make it more of a cash cow, in my humble opinion. Look at Craigslist: they generate the majority of their revenue from charging for a few sections, most notably job posting. I would suggest letting each user put up a resume for example, and charging a monthly fee for recruiters and other companies browsing this site to see the resumes, and purchase credits to contact the actual users with job offers. Just a thought.
