There are always people that are willing to give feedback. Subject matter experts often do via blogs, tweets, or even conversations. Some feedback is direct (intentionally towards you directly) or indirect (via the mass); some are solicited (you asked) or unsolicited (you didn't).

The stronger the feedback, the more there is to analyze. Lukewarm feedback generally yields tepid conclusions. Strong feedback there is something interesting, and worth sussing out

Feedback starts as a one-way street, and ends as a one-way unless you engage. If you nod your head at feedback, then the feedback loop ends there. If you ask for more details, the feedback loop continues. The latter is better use of time.

Feedback loops are independent of actions taken after the loop. You may engage in a feedback loop, but decide not to take action because you deem that feedback poor. Or you may wait until you get more feedback until you take action. The choice is yours.

It's important to orient yourself to take action after feedback - the action of waiting, no action, or action. Orienting towards action means there is a desire towards productive output. Even if no action is taken, that desire should be there.

Going back to choice, it's important to realize that you have choice; in fact that is the very purpose of the feedback exercise. The purpose is to train your own mind to make decisions, based on what you hear from experts, advisors, and people who "know". Because ultimately, the person who really knows is you, and the person who lives with the consequences is you. Everyone who gives feedback is just noise, and your job is to hone in on the right noise.
