This is the funniest thing I've seen all morning. Who was it who said that all posts on the internet that criticize someone else's grammar will contain at least one grammatical howler of their own?
That should, of course, be either:
"Don't get all whiny and moany just because you
can't use 'communicate' very well."
Or:
"Don't get all whiny and moany just because you
can't communicate very well."
