What percentage of the total decline in page views does this explanation actually account for? Beats me. It has to account for some though.
I did find this...
The number of active editors on the English-language Wikipedia peaked in 2007 at more than 51,000 and has been declining ever since as the supply of new ones got choked off. This past summer only 31,000 people could be considered active editors. - The Decline of Wikipedia
That confirms a decline in editors… and by extension… a decline in edits/pageviews… but no idea what fraction of the total pageviews decline it represents. It’s probably pretty small.
The Google explanation probably represents a much higher fraction. For a while Wikipedia seemed to frequently be at the top of numerous search results. This would of course equate to considerable pageviews. Now it seems like Wikipedia results aren’t as frequently as high as they used to be.
No data, like I said...
