Good question! We do have a lot of participants from not-primarily-English-speaking-countries, so perhaps one of them would be able to answer this better. However, this forum is filled with a higher-than-average number of quirky intellectuals, and we do love our jargon. Also, to seem more expert and smart, we even throw in technical jargon from our own respective fields! Okay, so there are actually good reasons for that other than showing off. But yes, I'd imagine the English here is very difficult as compared to even other smarty-pants forums on the web.
