i love the back and forth. its never personal with me(i would PM if it was). i write for the larger audience. some things get lost here and current users might miss things that arent in the top threads. its the nature of the beast.
as for the national conversation - forget it. people dont want to know about monsanto, they want to know the next line-up on dancing with the stars. its their loss.
keep posting. who knows who or what you will inspire?!
