It makes you wonder if sometimes people make opinionated comments on here just to elicit free lessons in some unfamiliar topic.

I mean, I do that sometimes. Once there was a thread discussing an app, and I wanted to know if the app has a certain feature. Instead of just asking whether it has that feature, I posted a comment saying "the only thing preventing me from switching to [app] is its lack of [feature]", thinking I'm more likely to get a response that way. And indeed right away I got a correction from an angry poster with just the information I was looking for. lmao
