It's clear that salaries and awards and grants are driving the increase in cost. Maybe this is damning evidence of a decadent culture, which the author of this op-ed clearly presume, but I doubt it. I would expect that Wikipedia's employees have been working very hard for a long time to keep the site running and they've cultivated expertise in governing the site in a way that avoids controversy and maintains credibility. I'd rather Wikipedia spend to retain long-tenured experts who have paid their dues than be an underpaid-college-graduate-mill like so many non-profits are. It seems that they've done that, and they've waited until the organization was financially stable to do so.
