Sometimes I feel like posting... sometimes I don't. Depends upon my mood. I find the responses very educational, not only from the information provided, but how a person posts. Personality can be indicated by how someone teases, posts a reply, gives advice and so on....
I have made some good friends at Pixies which I wouldn't have if I didn't post. That is what the lurkers are missing when they don't post or interact with members...
