Today, at around 18:10 EST, I noticed that the English version of wikipedia had just crossed over into the 1,000,000 qualified article realm.
Kudos, Wikipedians (and PHP users).
Update: preliminary guess which article is #1 Million (it's hard to calculate because not all articles qualify, and deletions are hard to track): http://en.wikipedia.org/wiki/Aaron_Ledesma.
It ended up being about a Scottish railway station... which is now a remarkable showpiece of parallel collaboration. --SJ
