From a reader:
I notice that some commenters have a icon or photo next to their handle. How does one go about acquiring this? Do you have to order a certain tonnage of Mystic Monk?
Yes. That exactly right. The more Mystic Monk Coffee or Tea you buy, the quicker and the cooler icon/avatar you get. Think of the kid’s cereal scams of yore.
Seriously, I believe people can get a Gravatar image to appear, if you get an account and upload the image.
