I know from reading Coding Horror one of the reasons stackoverflow set up was

No answers displayed, have to sign up and/or pay to see them.
Then google search for CSS scroll range and select the first result http://www.google.co.uk/search?hl=en&source=hp&q=CSS+scroll+range
If you scroll right to the bottom of the screen, there are the answers!
So in essence, if you are coming from google you can see the answer, if you go directly to the experts exchange site and search for the answer you have to either be an active participant and earn the right to see the answer, or get it directly by paying.
How/why aren't they penalised for this?
