This is the first in a series of posts about common-sense blogging protocols that I am making up as I go along.
This applies to both positive and negative descriptions. Don't insult people unless you are so convinced that it is necessary and proper that you would say it to their faces. Also keep in mind the Talmudic dictum to only praise someone partially in their presence. In general, assume that whatever you are writing will be read by the people mentioned and imagine yourself saying it to them.
Don't write something about someone you would not say to his or her face.
