Many of us are terrible at spelling and have grammar that would scare our 3rd grade teacher, but does that matter when we are just posting on our blogs?
Could you be judged or even miss out on getting a new customer because your spelling and grammar stink? Probably. Just see what Jan has to say over at Spelling Tips & Video to Share.
I may not notice your bad grammar, so unless you really screw it up, I'd be fine. LOL!
Just keep in mind that some others are not so easily forgiving for all those blunders.
