I believe that the addition of an edit history would be a massive boon to the usefulness of Lemmy on the whole. A common problem with forums is the relatively low level of trust that users can have in another's content. When one has the ability to edit their posts, and comments this invites the possibility of misleading the reader -- for example, one can create a comment, then, after gaining likes, and comments, reword the comment to either destroy the usefulness of the thread on the whole, or mislead a future reader. The addition of an edit history would solve this issue.
Lemmy already tracks that a post was edited (I point your attention to the little pencil icon that you see in a posts header in the browser version of the lemmy-ui). What I am describing is the expansion of this feature. The format that I have envisioned is something very similar to what Element does. For example:
What this image is depicting is a visual of what parts of the post were changed at the time that it was edited, and a complete history of every edit made to the post -- sort of like a "git diff".
I would love to hear the feedback of all Lemmings on this idea for a feature -- concerns, suggestions, praise, criticisms, or anything else!
This post is the result of the current (2023-10-03T07:37Z) status of this GitHub post. It was closed by a maintainer/dev of the Lemmy repo. I personally don't think that the issue got enough attention, or input, so I am posting it here in an attempt to open it up to a potentially wider audience.
I actually don't think it is required to trust people on a forum in the way you suggest.
If I was in what I perceived to be a really high stakes discussion (read: flamewar) where I was worried about this, I would take my own measures to ensure I could "trust" the other parties. I would save my own copies locally. Reddit RES had a button you could add client side for just this kind of petty bullshit. If you really want the feature, implement it in your browser/device.
Really though friend, try to have a bit of a sense of humor and distance from your online posting and interactions with unknown people. If someone is going to such lengths as to edit their post so it looks like you are responding to something else to make you look bad, it is either: a) a boring joke, or b) they are really pathetic and sad trying to sabotage you. Either way, it's not the end of the world. If it sticks in your craw, you can just go edit your comment to say "edit: the comment to which I am replied was substantially edited after I posted so what I said no longer applies". You can either delete what you said, or correct it, or leave it as-is with a caveat.
Why not try to improve it though?
I don't really understand the argument hat you are trying to make. You are admitting that this concern is justified, and that there are scenarious where one could be expected to want to take such measures, but you don't want a feature for this built in. Instead, you'd want a 3rd party plug-in...? I must ask: Why? Also, TIL about Reddit RES. Neat.
The point that I am trying to make isn't that this is for my own benefit, it is that this sort of behaviour detracts from the quality, and usefulness of the information on this site on the whole. Information shouldn't be purely ephemeral. The reliable exchange of information on forums is invaluable in the modern age. I couldn't even hope to count the number of times that I have gone through old forum posts reading people's opinions, and conversations when conducting research on a topic, or troubleshooting an issue.
I have been on lots of old forums too. That is irrelevant to this thread. This thread is about the ability to investigate the typos on the old forum posts. How often are you on some phpBB site thinking "this would be so much better if I could see what incorrect information was edited out in 2009."? Nobody fucking cares.
I don't have any comment on phpBB specifically, but I do frequently encounter the issue on old Reddit posts; however, it should be noted that the majority of the types of changes to comments that reduce the usefuleness of a post thread is their deletion, which is out of the scope of this post.
