Take a look at the "depth" column. Dutch and Swedish used to be your average Wikipedias, with article counts somewhere in the ~500k. They both decided that it was more important to have a higher article count so they now employ bots to create new articles with the bare minimum of data (sentence or two, pulled from other language Wikipedias). It usually becomes more extreme when there's some sort of milestone ahead. There's even worse offenders, for example Waray-Waray.
I'm genuinely wondering whether Wikipedia should have a policy of deleting all such articles and disabling their creation. I don't think it's in the spirit of an encyclopedia.
