Wikipedia reached its one millionth article today, and I was there on IRC watching as it happened... although actually I'd popped into the kitchen to do the washing up at the crucial moment.
Predictably enough the millionth article itself is not very exciting: Jordanhill railway station.
My own minor attempt to get article 1M was to create Ray Bradley and Phil Jones. But was then astonished to find myself in a delete-undelete war over the RB entry, on the grounds that he wasn't notable... unlike Jordanhill railway station. Sometimes wiki is a bit odd. To be fair, if you follow the RB link now its a better article than it was then. OTOH it may have been deleted again...
