After having ruthless professors and editors bleed all over my articles and essays for years (correcting them in red ink, for you non-writers) I learned that words must earn their space. I also learned:
1) Irregardless isn't a word.
2) You don't want readers to think about the words you write and/or ponder what you intended as the writer; you want them to simply consume and/or apply what you wrote. Unless you're a poet, in which case being cryptic can be good.
3) Spelling, grammar and style matter. BUT correct grammar doesn't always matter...
