Hmmm. As an amateur, I've often posted things on Cello Chat that were directed primarily to the amateurs among us. I never thought of it as being for professionals only, and never found their posts to be condescending to the amateurs.
If I were a beginning cellist, I would seek advice and suggestions from the most experienced players I could find, rather than from other beginners. So Bob's move seems sensible to me.
Pace, daisyrose. I hope that you'll find that Cello Chat can be a home for you.
