This is something it's taken me a while to come to terms with. I used to want to fully engage with everybody and everything. It was anathema to me to just "broadcast something into the void" and ignore replies. But over time I came to realize that a. I don't scale to engaging with every single person who replies to something I say online, and b. I don't owe those people a response or any of my time/attention; especially the trolls and bots and other lamers that are so prevalent these days.
So now I'm more comfortable (albeit maybe not 100% comfortable) with treating things in more of a "fire and forget" fashion. I say what I want to say, and people can do with it what they will. I just can't be arsed to engage with the trolls and other randos. But... if somebody has a mature, reasonable, professional response then I am willing, on a selective basis, to dig in deeper and have a longer discussion.
