This thought was brought to you/sponsored by my perception that there's an increasing number of comments on Tildes that attempt to "answer" questions posed in the titles of posts, but don't necessarily demonstrate that the user has read the article before commenting. I won't link specific comments, but I've noticed a fair bit of it as of late. I get that those titles bait people into voicing their opinion, but often it's at the detriment of overall discussion. Should a prerequisite of clicking the actual link in question be a requirement before the user is allowed to post a top level comment? Or perhaps a cooldown period of entering a thread versus commenting may help?
The goal here would be to disincentivise the posting of "driveby" or similarly reductive comments that often don't demonstrate nuance or knowledge that is conveyed in the associated article. Sure, we can't ever know if the user has actually read the article, but it's not designed to be a foolproof strategy, just a discouraging one.
Just to clarify since I've edited this post: I mean top-level comments only. Replies are more likely to be in response to the parent comment, rather than the title and wouldn't be affected by this proposal.
