Regarding Internet ETIQUETTE: Would you see if this is CORRECT?
Now, is this proper USAGE???
1. ha = Yea, Right!
2. haha = not funny, keep trying
3. hahaha = sarcasm
4. hahahaha = ??? (I've seen this used only once so this one's wide open to speculation)
5. hahahahaha = genuine laughter
Please make any corrections you feel are necessary.
And FINALLY, are there upward limits of ha that become socially unacceptable?
