When was the last time you answered a Lemmy or Reddit post/thread that was more than five months old?
I think there should be some incentive for that, like make those kinds of comments a spotlight or something. Maybe make a community called "late replies" that showcases the best such replies, or have a rule saying they grant free karma (in Reddit's case).
I think the term would be "necrobump", and Im not sure why you want to encourage it? If a thread is active for 5 months sure, but otherwise everyone has moved on...
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.
Its not a global bump, but it does bump it back into conciousness for the person being replied to. Ive had it happen a few times on lemmy, and its always so confusing because i had completely forgotten what i had originally said.
I'm not against necrobumping in certain contexts. If I have a tech support question, I can promise you I'm still clueless after 5 months. Also a niche creative project can take over 5 months to find it's audience, and creators are usually happy to hear feedback.
Answering an unanswered question is definitely valid. Feedback for a niche creative project may be better served by a new post, but a late comment is fine as well.
I dont have a problem with necrobumping, but i dont think it deserves to be promoted or incentivesed in a "bestof5monthslater" showcase.
Anything that can be gamed for imaginary internet points will be abused, and it wont be long before there is a flood of "Upvote if your still reading in 2025 🥳🤠🤯" comments.
I haven't recently, but when I am trying to solve a problem and come across a post/comment which does a great job of helping me out, I'll sometimes post a "thank you" to the author. On the receiving end of things, I had posted a couple of kinda useful scripts in the PowerShell sub-reddit and would get both "thank yous" and questions regarding those scripts from time to time. I also had a really popular post (it's still linked in the wiki) in the cordcutters sub-reddit which elicited questions years later.
If I see the person still active on the platform I'll try my luck. Otherwise if it seems like they are the only ones on the whole internet who (possibly) knows how to help with my problem, but that'll more likely result in a DM.
Within the last year, I've definitely had some replies to old threads of mine. And if it's a question, I'll respond. And I think I did comment on another's thread at least once, confirming and thanking them for the solution. All of these were tech support related. I feel like that's one of the few topical areas where that's acceptable.
