Definitely understand where you're coming from... It's kind of a double edged sword, because while we agree with you that lack of self confidence is an obstacle (and one that it took us a long time to overcome), positive feedback definitely helped a lot with it, leaving us in a better place than if we had not done it.
As for your feeling regarding too much of this or that, again we get where you're coming from, but we feel like that should not really matter as long as you want to post :) People liking it will want to see, others won't, perhaps they'll filter it, but you're not forcing anything on anyone by posting, and people can curate their feed however they want to !
Sidenote, if you want a more confidential environment to talk and/or share, our DMs are open :)
