So perhaps it's something about the way the Polish Wikipedia works? A
few thoughts:
* Polish doesn't host any images - unlike most other projects - so
there's no need for image pages, image talkpages, etc. On some
projects, such as German, as many as 6% of pages are in the image
namespace!
Yes. We sent all images to Commons. We finished this work last month.
* Polish doesn't seem to use article talkpages much. I've just spent
some time hitting "Losuj artykuł", and about 10-20% of the articles I
found had talkpages. In English, this is about 85-90%, and in French,
about the same. In the other languages these may just have project
tags ("this article is part of WikiProject Something") or metadata
("this article is rated C-class and needs an image"), but they still
show up as non-article pages. There's currently ~735,000 articles and
~595,000 non-articles; if another 70% of articles were to have
talkpages - making it comparable with English and French - this would
make ~1,110,000 non-articles, or 1.5 non-articles per article.
Readers who find errors use "Zgłoś błąd" (notify an error) in menu (sidebar)
rather than talk pages.
~1500 edits by month (notifies and answers):

Old talk pages with solved problems are deleted. Talk pages of dynamic IP are deleted too
(we wait ~6 months and delete them by bot). I don't know - is it standard behavior in
other Wikiepdias or specific for pl.
* Finally, Polish Wikipedia has fewer active users than any of the
next three "smaller" Wikipedias - Italian, Japanese and Spanish -
which might be significant here. Fewer users talk less, so there's
fewer "natural" discussion pages.
True - we have only ~300 very active users. We rather use main. One of the most often used
slogan is "we work here, not talk". Many times we spend in "flagged
revisions" - so, we are sure, that 90% are free of vandalism.
