Alas, judging a language edition by Wikimedia Statistics does not work.
Indonesian, Asturian and Volapük WPs have the same "depth" (8), but id.WP is a very good WP. How comes? There not so many edits per article in id.WP, because it has translated a lot from English. A legitimate way to create (good) articles, but it does not need a lot of edits.
Bot activity: Indeed, "bot bumps" can often easily be detected in stats tables. Especially the small Wikipedias (I suppose) show (relatively) many bot activities due to interwiki linking. On the other hand, pseudo articles can be created by hand (let a script create it outside WP and then insert it "manually").

Hi Ziko. Standard of article in pl wiki is 1,5 kb (in 2008)
http://tools.wikimedia.pl/~warx/dnb/index.xml
500k is nothing for us, but is good event for PR and only it. If we have good PR we have more new users. I can't see "count obsession" in pl wiki. I se other obsessions - copyvio, POV, vandals, trolls, lack of sources etc. Users in pl wiki know how others look at them. Believe me, we try be better, but our community is not huge.
