[Old Tele man]

...there *is* a difference between "selling" and "convincing" just as there's a difference between "...trust me..." and "...show me..."

...yes, I'm interested (as stated earlier), but so far I haven't read anything that tells me in convincing terms that it actually works and would provide tangible benefits...to me. And, as a reader, I believe that makes me one of your 'target' audience...or, maybe not?!?

...isn't it the authors' task to provide the words that makes the reader believe and understand? The reader should not be "left" wondering "...is that all there is?" (sorry about the Peggy Lee pun).
