Article Count
9: Some Wikipedias contain massive amounts of bot created stubs,
    (e.g. Dutch Wikipedia 42% of total, Volapük 92% of total)
    which makes article count a questionable metric of community effort.
    see also new report on bot induced article creation activity per wiki.
New Articles Per Day
10: Sharp drop in overall number of new articles on all Wikipedias combined mostly due to bot inactivity
    on Dutch Wikipedia, which in Dec accounted for 33% of all new articles.
11: Still this month the number of wikis with exceptionally large numbers of new articles rose sharply:
    New articles per day for Dec->Jan: Slovene 33->312, Bashkir 4->308, Malagasy 3->232,
     Latin 45->215, Armenian 31->123, Fiji Hindi 22->83
    For comparison, two large Wikipedias with normal article creation rate: Russian 348, Spanish 285
All = All projects, Wp = Wikipedia project   /   B = billion, M = million, k = thousand
