(Electronic / Computer) Copyright?

You will, or will have, seen I put a © in my signature. 'cause I'm checking things out and experimenting, and 'cause I could. (-:

I myself have advocated in the past that using c. in this manner, particularly in e-mail, is silly (extraneous), annoying (something extra to be read), and pointless.

Pointless because if you do not actively defend your copyright, you have no copyright.

I'm probably a little paranoid as I have seen, all too often, innocent e-mail's get forwarded all around in a circle, causing all sorts of aggravation of all different kinds.

Let alone, being a web page, how one can google and get the darndest things. Our content will come up. I've seen how things can be twisted. ("causing all sorts of aggravation of all different kinds.")

richard blog's "what to do, what to do", about copyright. Heck of a question! Certainly no easy answers.

Anyone with thoughts on this? (Corrections?)
