Language habits (including writing) are developed early and are heavily influenced by the parents (or home environment). The children of college-educated parents are likely to be much more articulate and possess better language skills than their counterparts (with non-college educated parents) even with relatively equal educational exposure outside the home. No surprise there but that's not to say that this handicap cannot be overcome. First, one must actually CARE how their written presentation comes across. Since this is usually the only exposure we have to our 'cyber' friends, you'd think one would want to put their best linguistic foot forward, but apparently not.
Long run-on sentences with NO punctuation are torture to read, and leaves one wondering about the intellect of the writer. In most cases, I think it's just a case of the writer's brain racing ahead of his fingers (although many times the opposite is true

). Anyhoo, where's that 'spellcheck' button. I was just thinking; too bad there isn't a 'music-check' button we could push before we posted some of our musical offerings. Just a thought.
