We have a status-completed tag. Why are titles being cluttered up with their status? Are moderators not responding to flags asking to have things marked status-completed? I find this is really decreasing the readability of meta for me.
The status-completed tag can only be added by moderators, and we get a lot of questions here asking for specific actions on questions (close, reopen, delete, fix...). Asking for the tag creates unnecessary work for the moderators when the community has better tools.
As I wrote previously, the best solution to this problem is an accepted answer. An accepted answer is the standard SE way of saying "I got the help I needed". I agree that as the number of these questions increases, the edited titles are making meta harder to use.
I would prefer that we leave the titles alone and use answers. I didn't object to editing titles before, but there were fewer of these requests then. People, please use answers for this. The OP can add an answer and then accept it, if nobody else has added one.
Requiring an accepted answer needs two users input rather than one. It needs to be both answered and accepted. Which can create a big delay depending on when an OP is available. We have large disparities in timezone.
(Done) can be entered by any user with editing rights, and as far as I can see is done as soon as the last reopen vote is cast or an interested person sees it has been reopened. This immediately shows everyone they do not need to action anything here and can scroll past.
It also highlights a particular concern we have been looking at lately. But it's greatest advantage is that users will not waste effort entering a meta reopen request, then finding the question, and then finding that it's already been reopened.
In my opinion this has less of a negative affect on the 'user experience' than other options. I actually see it as a positive and proactive solution, but that is just my opinion.
It's not ideal, but it is the easiest way to make it clear that something in Hot Meta Posts has been reopened, or that some other action has been taken (so people don't need to waste their time looking at it).
If you view question lists on Meta, an accepted answer would be comparable (in terms of effort required and visibility), but this wouldn't be visible on Hot Meta Posts.
I mentioned some of my thoughts about this in another post. The TL;DR is that the "better" solutions would involve system changes.
