I agree with both him and you. But I think part of his point is that often times HN comments tend to focus on kind of irrelevant stuff. I'm the author of this post and the top comment here bothered me a bit because it has nothing to do with the content of the article itself, it's just the top commenter giving his opinions on what types of dungeons he likes better. I didn't even post the article to HN myself because my past experience with comments here (https://news.ycombinator.com/item?id=7540555) were similar in that discussion tends to not be that meaningfully related to what was written.
Thanks for making the post. Sharing knowledge is great and I appreciate it.
I've written a handful of educational posts as well. I swear the majority of comments only exist to make the commenter try to show off how much smarter than the OP they are. Reddit is the absolute worst. But HN isn't far behind.
I'm sorry the top comment doesn't actually provide any value to any one. Please don't let dingleberries like him prevent you from writing more in the future. Thanks for sharing.
