Bernard Baruch's famous quote-turned-cliché, "Those who matter don't mind, and those who mind don't matter," becomes quainter and more obsolete by the day. Technology has made the public-communicating elite more accessible, and as a consequence, more vulnerable to critique. Feedback lurks in every corner – your inbox, your @replies on Twitter, Facebook, comment sections. If you choose to ignore the criticism, people will inform you of it nonetheless ("Don't let ‘em get you down," they will say.) If you are sensitive enough to be sourcing your emotions for content, you are probably sensitive enough to be affected by these words, especially when they are negative. You may even end up exploring them, sorting them out or just plain responding to them in your further work, which will then be up for public dissection, which could get under your skin some more, causing you to react again, etc. Modern discourse is full of noise, thanks in no small part to these feedback loops.
