I must be incredibly fortunate, I got a lot of good value from SO and have not experienced any of the toxicity that the author mentions here. I have written questions, comments, and answers.
Stupid people hated stack overflow because it didn’t allow them to be lazy.
This was my experience using StackOverflow. I've commented, asked questions, and received answers. Aside from a few questionable downvotes I received occasionally, I never felt like the community was toxic.
