Most of the reactions I have been receiving lately have been suprisingly positive. I've had several people ask questions, want to know how difficult it is, how do I manage all the toons at the same time, etc.

I did have one person stop and ask me if I was a chinese gold farmer. My Response : " We've tried farming chinese gold, but we can't tell the difference between it and regular gold." He laughed, wished me the best of luck leveling 5 toons at the same time, waved, and went on his way

If someone gets really obnoxious, just ignore them. Seems to be the best policy.
