I have seen this used by Social Workers and Grievance Studies types and it comes off like the Bowery Boys. Simple concepts expressed in other than simple language for any reason other than to provide clarity in meaning are mere obfustications.
99.99% of the post in here I can read and understand the posters meaning and intention. There are a very small few who think using a lot of words which most persons never used nor for that matter most in higher education never used except in specific rare cases makes them seem smarter. Many times if you look the words up and connect it with the subject it's gibberish LOL. I've seen it done in one forum in here I'll not mention.
A persons region they live in also influences their language and grammar especially when using phonetics to spell. Local dialects have more influence than English books in school. If you go to Louisiana you'll hear a dialect many can not understand. If you send someone from Tennessee to Boston or New Jersey you will see a person struggling to communicate. But I also noticed after about a year in the Navy everyone seemed to loose their dialect somewhat except for foreign nationals.
When I was in school the word "ain't" drove teachers nuts LOL. Now it is accepted.
The second, I had to say everything three times and write it down twice to make myself understood.
After learning to speak like Johnny Carson, I had fewer problems...
