I think the term would be "necrobump"

That's from old school forums where posting to a thread bumped it back to the top of the feed and thus thrust old info prominently into everyone's view again. You won't get that same bump effect with most sorts on Lemmy. ("New comments" sort might work like that though? I'm not sure exactly how that's handled.)

otherwise everyone has moved on

It's pretty rare to get much of a response even after just 24 hours or so -- not just in terms of comments, but even for upvotes. I think after that point, posts are usually so far down people's feeds that almost no one sees it any more. That probably also discourages most people from replying since basically no one will see it. (Maybe the poster of the thread or comment you're replying to will see it, but probably almost no one else will if it's more than a day or so old.)

Some people do dig through community archives and/or user profiles -- particularly after a new thread is posted -- and they'll occasionally upvote old posts, but they very rarely comment.

Just the other day, I got a reply to a thread from ~6 months ago on kbin!

It was spam. :/

I've seen 20+ car crashes outside my window in the last few years and cars usually either stay right where they stopped until police (and later tow trucks) arrive in the case of serious accidents or else pull over to the side of the road to exchange insurance information in minor accidents. In some of the moderate cases, I've seen the drivers try to move their cars out of the way of traffic but they still stay at the scene. I've never seen a car pull into a parking lot after an accident despite there being one literally right there where I live.

I quit YouTube along with reddit last summer. I don't use alternate interfaces. I haven't found a replacement for most of the niche content I liked to watch there -- and yes, that sucks.

I've mostly been watching offline content (like DVDs and things I downloaded years ago) when I want video entertainment, and doing other stuff with my free time.

You might think that'd mean more time playing games given my interests, but I've found I'm a lot less enthusiastic about playing through games if I can't watch an LP or two of it afterwards. So, I'm actually playing (and also buying) less of those than I used to too.

The Japanese text on the bottom of the left image says: Sapporo (Draft) Black Label beer. I can't tell what the four characters under 生 are though. (Too blurry for me to figure out.)

Edit: those characters might be 非熱処理 -- meaning unpasteurized.
