Stupid!!!!!!!!!!!!!!

I have been reading lots of forums and I am wondering about their passion for using difficult words and real long sentences. Before I reach the end of the sentence, I am out of breath and have lost the point entirely. Oh my gosh! Have my brain deteriorated and suddenly became stupid? My teachers told me to keep sentences simple and to the point. Keep It Simple, Stupid was an ever famous acronym from Kate. Simple and less words to a sentence makes your idea sharper. That was what I thought before I began reading forums where nowhere-but-in-the-dictionary-will-you-find-such-words dripping out of their mouths like saliva to a crazy dog. I don’t read as often as when I was in college, but when I do get a chance I get the meaning fast enough. Have I been in front of Excel/Access too much!? Have I played RF way too much?
