Every time I find an old (sometimes just more than a few months) post, a lot of the comments have already been deleted (by users and sometimes mods). I'm more likely to add site:news.ycombinator.com than site:reddit.com to my query because of that. HN is smaller, but at least the discussions are always preserved.

I wish websites were less lenient on letting users delete posts/comments. I much prefer the HN model - no delete button, you have to contact moderators and you need a good reason, you can only delete individual comments, not an entire account.
