That's the beauty of communication and the free internet, what a joy to learn about someone elses way of thinking, add a little colour to my world view.

One of the things I miss most about the days of IRC chat networks, the personalities were big, broad and diverse, all mixing together. If someone is a narcissist, so be it, they still have value, knowledge, opinions to share. Online discourse these days can verge on corporate approved, totally empty. Apologies for the tangent.
