Good writing demonstrates not merely your level of education, but also consideration for your readers. As Blast points out with a humorous example, sometimes a tiny punctuation mark can make a big different in meaning, and those who intend on imparting tips on survival surely want to be as clear as possible.

No, we need not live up to the professional standard of a publishing house, but we can strive for clarity and readability. It's not too much to ask. As readers, we respect the time that people took to write their postings to share their thoughts. Naturally, as writers we must also respect the reader's time. Don't make it difficult for your readers.

Let's face it: people who write poorly and carelessly don't deserve our attention. They are ignorant jerks who waste our time.
