It is always taught to use simple English in day-to-day life and I follow it carefully. As a student in IT sector, I use simple English myself as this particular industry does not revolve around beautiful English, rather the core subject only. In my spare time, I write articles and ebooks for various clients through a website. But it is my personal observation that, not only non-native people, but also native people are more inclined to those articles which include most of the so-called sophisticated words. They reject those articles easily which use simple and normal English; yet makes no delay in accepting articles with hard English.

Thinking from non-native mindset, using harder English can help getting more respect as it shows the knowledge level of the speaker in a foreign language. However, I can not see any logic for native people to be inclined to harder English. Is this phenomena an exception? Or it has some base?
