Liz is a Linux enthusiast. She uses Linux as her only operating system for the last two decades, and she is very knowledgeable about it. She is keen to help other Linux new-comers solve issues they run into frequently.
Liz opens !linux@lemmy.ml today and comes across yet another post about a potential new Linux user trying to choose his distro. After ten minutes reading through his post, she finds out that he is only trying to run AAA games on the computer. Liz opens up an identical question she just answered yesterday, and pastes the answer over to the new post.
Liz wasted ten minutes on this post and she is now depressed about it. Liz has the ability to contribute to the community on a deeper level but she cannot do that except she reads through every post first.
Tom is a fellow Linux expert and he feels the same way lately. Coincidentally, Tom and Liz both wasted ten minutes on the same, generic question about choosing a Linux distro.
Hypothesis: If Liz has a way to notify Tom about that post, Tom would have saved ten minutes. Imagine that both Liz and Tom put up a tag on that post for others to see, countless other experts would have saved countless minutes.
As a subscriber of a community which has broad topic selections, I want to tell other viewers that which kind of post this post is, and also know the kind of post before I even read into it, so that everybody saves some time.


tags are (on other platforms) a part of a post’s content. This means that every user creating a post has to attach every tag that is relevant to the post, which could be a lot of effort if there are many tags available.
It would also be interesting if other users (e.g. moderators) could attach tags to a post, i.e. the post exists independent of the tags, and the tags get applied after the post is created.
