Great point. As somebody who has been in the crosshairs of Wikipedia mods (see ANI) my bias would push me to agree :). However, despite what I see as problems with Wikipedia mod culture, it remains true that Wikipedia has grown quite a bit, both in number of articles and length of already existing articles, over the time period when pageviews declined. I suspect the culture is probably a factor in that it represents an opportunity cost: a better culture might have led to an (even) better Wikipedia that would not have declined in pageviews so much, but I don’t think the mod culture led to a quality decline per se. In other words, I don’t think the mechanism:
counterproductive mod culture → quality decline → pageview decline
In the case of Wikipedia, I think the aspects of quality that correlate most with explaining pageviews are readily proxied by quantity. Specifically, the main quality factors in people reading a Wikipedia page are (a) the existence of the page (!), (b) whether the page has the stuff they were looking for. I proxied the first by number of pages, and the second by length of the pages that already existed. Admittedly, there are a lot more subtleties to quality measurement (which I can go into in depth at some other point) some of which can have indirect, long-term effects on pageviews, but on most of these dimensions Wikipedia hasn’t declined in the last few years (though I think it has grown more slowly than it would with a less dysfunctional mod culture, and arguably too slowly to keep pace with the competition).

(c) whether the information on the page is accurate.

Except not all topics and not all information are of equal interest to people.
FWIW, my impression is that data on Wikipedia has gotten somewhat more accurate over time, due to the push for more citations, though I think much of this effect occurred before the decline started. I think the push for accuracy has traded off a lot against growth of content (both growth in number of pages and growth in amount of data on each page). These are crude impressions (I’ve read some relevant research but don’t have strong reason to believe that should be decisive in this evaluation) but I’m curious to hear what specific impressions you have that are contrary to this.
If you have more fine-grained data at your disposal on different topics and how much each has grown or shrunk in terms of number of pages, data available on each page, and accuracy, please share :).

You seem to be conflating quantity and quality.
