These TL;DR comments bother me tremendously, but I can't quite articulate why. I feel like maybe it bugs me that someone takes the time to post an interesting article and a comment with nothing more than a summary implies that the article is not worth reading.
I even looked in the guidelines for comments to see if it's discouraged, but didn't find anything.
I realize that communities grow and change over time, so maybe my opinion is uncommon. What do you think?
Scientific papers have abstracts. Business and government papers have executive summaries. This is not an unusual thing. So I ask: Is it the practice that bothers you, or the label we use to signal it?
