Wikipedia founder Jimmy Wales underscores that Bomis, his dot-com search engine business, was not directly involved in pornography, pointing out that its content was R-rated rather than X-rated, like Maxim magazine rather than Playboy .
Wikipedia underscores an evolutionary lesson: We've always gotten farther as a species collaborating than going it alone. [...] In the past, the groups that cooperated best lived longer and had more kids – and we inherited those tendencies. Groups would correct cheaters (people who didn't share info or goods) through social pressure. So Wikipedia is like humanity's social nature writ large electronically, complete with ongoing disputes and corrections.
