right, that's a valid observation and obviously it's important. The other thing you have to keep in mind, is that many of the people around here (read: contributors) didn't learn English as their first language. Also, people with a background in computing/software (or IT) are obviously pretty likely to use a certain lingo/jargon due to this very background.
Fortunately, we may be in luck, since tfreriks stated that he is indeed not just a former software developer and a pilot, but also a professional writer
Seriously though, it would obviously be appreciated to review/tweak such problematic paragraphs/articles, but it's also important to keep in mind that they should remain accessible to people whose native language isn't English, while also still using the technically-correct terms (if in doubt, included in parentheses).
As you may have seen already, we do invite native speakers to help review/improve and proof-read contents added by our community, especially referring to some of the more prominent contents (think newsletter or release announcements)
Again, none of this is to suggest that I disagree with any of what you said, it is just to say that there is a very real bottleneck issue here, i.e. the number of people contributing to the project is not equal to the number of native English speakers.
