Two more points for consideration: . The veracity or otherwise of the Britannica is a red herring. We are talking about Wikipedia. To claim that Wikipedia is reputable on the grounds that the Britannica too has a credibility problem is an example of the fallacy of ignoratio elenchi. . I'm inclined to agree with Howard on the issue of whether experts have time to contribute substantially to Wikipedia. My argument is the smell test. Tony, as an academic, is likely to agree with me that academics get little time to research these days. In the past, we had 50% teaching time and 50% research time. Nowadays, it's more like 65% teaching time, 35% administration and research . well you do that in your own time. Now I don't think it's too much a leap of logic to suggest that knowledge is more likely to be found in academia than elsewhere. It is not so universally, but it is so generally. You don't find the smartest physicists outside universities, nor the smartest linguists, nor the smartest philosophers. Very few private sector organisations give free rein to intellectual pursuits and blue-sky research. Now if the experts are more likely to be found in academia, and they are pressed for time to advance knowledge, just how likely is it that they will devote their time to monitoring and updating Wikipedia entries. A Wikipedia entry gives them no professional acknowledgement, no citation credits, no likelihood of accelerated career advancement. So why spend time on Wikipedia when they could be spending the time writing papers for journals that will give professional acknowledgement, citation credits, and accelerated career advancement? I've asked 14 of my colleagues at Melbourne University whether they have contributed to Wikipedia. Not one has. It's not a question of money, as someone on this thread mentioned. It's question of securing a tenuous hold on an academic posting. That takes a lot of time. Papers in peer-reviewed journals count. Wikipedia contributions do not. To put a not too fine a point it: few academic experts seem to be bothered contributing to Wikipedia. They are just too busy. So who are the experts contributing to Wikipedia? Scotch-soaked grogblossoms in second-rate universities living out tenures who have no hope of achieving intellectual acclaim? Or also-rans who are making up for their personal academic disappointments? Or am I being too harsh?
