This "make a second draw" approach would also let you tune how often you
saw the "bad" articles. That is, if it's a bad article, then flip a coin
to see if you should make a second draw. Repeat if the new article is bad,
but never make more than N draws. Someone with time on their hands and a
statistical bent could compute how often "good" and "bad" articles
come up
as a function of the ratio of good and bad articles, the coin flip
probability, and the limit N.

Interesting. An even easier/coarser approximation
would be to make a second draw only when the
first draw doesn't meet some criteria (e.g.
bot-created, shorter than L bytes, lacks illustration).
On an average day, Special:Random (and its
translation Special:Slumpsida) seems to be
called some 9000 times on sv.wikipedia
