My opinion is that if your biggest contribution to a thread is harping on someone's grammar, spelling, punctuation, etc...you'd be doing everyone a service by not commenting in the first place. You can deal with it and try to contribute something of value pertaining to the subject at hand, or you can move on to the next thread. Not saying it's the case here, but not everyone has been afforded a solid education, or has the capacity to proofread their own writing. Not everyone is capable of wording everything so eloquently either.
If it's that bothersome to you, I'd be glad to point you to a couple very well known breeders that have crap grammar...maybe you'd be nice enough to send them an e-mail asking them to present themselves in a more professional manner as well.
