Newbies or Better information?
I wouldn't argue that because Wikipedia is a top ten website, the people who have contributed to it are experts in how to build one -- or even know more than the average person about this trick. Offer a product or service which meets or exceeds minimal standards of quality for free (as in beer), & you will find a ready market. Wikipedia's success was due to filling this niche.
No one connected with Wikipedia should consider ourselves geniuses just because we managed to be at the right place at the right time. Not even Jimmy Wales. Although almost of us commit that logical fallacy. Including Jimmy Wales.
