I've been on the internet basically since it was invented (well, since Web 1.0) and am generally a fan of open access, democratizing knowledge production and distribution, and copyleft (but also attribution, accountability - hence my real name - and people being paid fairly for their work, though that last one is a bear).
I was highly skeptical of and resistant to Wikipedia for most of my academic career. I've changed my mind and am here to make it better, because:
Wikipedia is already serving as the de facto source of information on the open web—it effectively has no competitors since it's privileged by Google (not without valid reasons), which in turn determines what most humans on this planet read.
Wikipedia is a 21st-century solution to knowledge management that's capable of wide reach, global implementation, and continuous expansion and updating;
Wikipedia is fast, cheap, and good: that is, comprehensive, free, and reasonably accurate on most topics.
