Well, as noted, the point is
to communicate. Proper sentence structure, grammar, and spelling all go towards that end, but one must also consider the target audience, and i suspect that most of us are a lot more interested in the ccntent (substance) than the structure (form).
Though poor grammar and spelling make reading some posts like driving on a bumpy road, hopefully you still reach your destination, that is, get to the point. Bear in mind, though, that if the journey is painful, or the road's washed out, some may not make the trip, and we all lose.
All in all, it's a minor annoyance, as I have found this place full of interesting, good-hearted people, so all y'all keep on keepin' on!
Today's lesson: there vs. their - "there" is a place, as in "set your guns over
there.: "Their" is a plural possesive pronoun, as in "they set
their guns over there."
