Man I would love to see some statistics on questions and answers on the evil hyphen site (as Joel calls it) since Stack Overflow came onto the scene.
You can register for free at Experts-Exchange. It only costs you to ask questions if you haven't already answered some. And once you've answered a few, you get a very low-bandwidth view of it too.
I'm not saying the site is brilliant, but I don't think it deserves quite the bad press that it gets.
I've been an Experts Exchange member for about 9 years now. I haven't been very active there for a while, though. I lost a bit of interest in that site since my favorite topic (Delphi) has become less interesting and most questions have been asked before and thus repeat themselves. Still, I've never paid for this site and have earned four t-shirts and a $100 prize from them by answering a lot of other people's questions there. It also gave me enough points to ask a new question there every day for the next 5 years, if I want to. Then, of course, membership of EE can be free if you earn enough points per month to be recognized as an expert. And to be honest, if they would make every member with over half a million points (like me) a permanent member, I would probably be more interested in EE and less in SO. It's just that I don't want to spend every day on EE trying to earn points so I'm a free member for just another month.
