On en: vs de:
From my experience, two (rather unrelated) differences
are most striking:
(A) On de: the argument "no real (convential) encyclopedia would write this" is by and large honored (or at least considered). On en: this argument is ignored, or even considered trollish.
(B) On de: all articles are expected to be accessable to a general audience (the horrible and horribly named "Oma-Test" -- "grandmother test"). On en: there are a lot of articles in mathematics and physics addressed to users definitively having some education in the area. I assume most experts are flocking to en: anyway, as it seems pointless to have advanced articles in other languages than English.
