Another advantage that can't be overstated is that of checks-and-balances: 
if any one of the tutors here gives erroneous advice, the other tutors 
here will provide error-correction.  (I've had this happen for myself 
several times, and I'm grateful!)

Contrast this situation with depending on a single authority who might not 
necessarily know what he or she is talking about.  So there's a strength 
and reliability in a public forum like this that you won't easily find 
from private tutoring.
