Well said, Isabella. May I suggest only one addition? That would be, "...even if most of it seems to go unheeded..."
Just as someone pointed out that legitimate subs may well not speak up for a variety of reasons, legitimate subs (and perhaps "attention whores" that are actually real subs underneath) may well take the advice to heart without ever alerting anyone that they have done so.
A good and honest word is always well said, whether thanks result or not.
