On the other hand, the Heaven's Gate cult made many references to Star Trek in their material as well, and the franchise enjoyed major popularity in Germany, I would wager beyond other non-English language spheres. This may also have increased the size of the potential receptive/interested audience.
In the back of my mind I have a maybe-never project brewing that would entail finding Wikipedia pages that only exist in one language. English would of course have many unique pages. I wonder how many non-English page translations would be rejected on notability grounds, just due to sheer cultural differences.
This makes sense, because if one wiki has, say, 60% of the content (and depth) of some other wiki, it will break it down into pages differently.
Being able to speak both languages, I often find it instructive to browse the pages on a subject on both English and German Wikipedia, as the structure and depth of the material will often vary either way. It's sometimes unfortunate, but other times also possibly warranted that these wikis cover subjects to a different degree.
For example: "for starters" is translated as "für Starter" which does not make any sense.
