I can't tell you how many emails or PMs I get from people who are afraid to post their questions here so they ask me privately.

I haven't asked anyone why they are afraid to post  but I'm sure that noticing the responses that some other people get is a factor.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
