Another of my pet peeves

The internet has made reading newspapers an interactive experience. Some online newspapers, particularly Houston Chronicle and USA Today, offer a format in which readers can comment on news articles, editorials, etc. Certain people comment repeatedly; often their comments are full of misspelled words, awkward grammar, and incorrect punctuation. This tells me the contributors are either uneducated or too goddamned lazy to write a proper sentence. Either way, it's something I consider when evaluating the merits of their arguments.
