Just as real estate has its ‘location, location, location’, writing has its punctuation.  I cannot stress this enough.  Perhaps I’m too picky, but when people don’t use proper punctuation, it takes all my self-control not to scream.  Proper punctuation makes whatever you write easier to read and understand, besides giving your work a more professional feel.  If your sentences are similar to a kindergartener’s, it’s rather hard to take it seriously.  Without proper punctuation, everything looks and sounds sloppy, and shows indifference and lack of effort on the part of the writer that is palpable to the reader.  Not to mention that publishers want work that’s well-written, and a big part of that is punctuation.  So please, for the sake of picky people everywhere, use proper punctuation.
