I'm designing an experiment and want a random sample of wiki articles. The 'Random article' seems like a convenient way of generating these with having to compile a list of the population of articles myself.
My hunch (based on clicking it lots and very little else), is that 'Random article' is a uniform sampling of pages in article namespace, excluding redirects but including disambiguation pages. As implemented on en.wiki (which is the wiki I'm starting on) it probably has a slight bias against very recently created pages (due to cross-server synchronization).
Has anyone looked into this?
