I think there's something relevant going on with search optimization, or if you prefer, marketing and advertising. A Wikipedia user who is somewhat active just now is using mentions of the website to boost the references to a particular consulting firm. This sort of activity is not much beloved by many habitues of Wikipedia, as you can see in the essay <a href="http://en.wikipedia.org/wiki/WP:SPA" rel="nofollow">http://en.wikipedia.org/wiki/WP:SPA</a><p>Here I'll leave it to others whether this is smart and laudable or sneaky and regrettable. Perhaps it's normal and unremarkable, but I find it interesting. It is only a guess on my part that this is intentional and coordinated.
