In and On are different words with different meaning.
Just as Michael Green made me think about what he wrote, albeit his topics were worth considering if not completely agreeable upon, you made me think, too, and I think I am slowly realizing where you are coming from.
Glancing over the references you post, words you repeat, forum you decided to express your opinion on (or in, if you prefer that option), mysterious quizzes full of unanswerable questions, and passion you have for a few of these, there is only one place you may be coming from.
This last Zen copy you provided us has many features of a check-out counter literature. Words chosen to leave the reader breathless, some romantic hints, wisdom for everyday life, fight for the truth against "the cruel world that does not understand us" and, above it all, passion. Such literature deserves Fabio on the cover and that is what gave it away. It all came together.
The answer to your well-crafted and unannounced quiz is.....
Target (store).
You did good this time. You gave us all those subtle hints and we did not even notice. We thought you were not making sense, but you outdid yourself this time.
Congratulations. Say hello to Fabio from the rest of the Audiogon bunch. Is he really as friendly as his interviews make him appear to be?
