Users whose own posts are edited are already notified. However, I would like to propose that, where I edit someone else's post, I can choose to be notified of subsequent edits. Or, perhaps these could appear as a new tab in user profiles, without raising a notification.
The purpose is thus. I often edit questions to improve clarity, trim noisy I've-searched-for-this introductions, remove salutations and signatures, and fix txtspk or spelling, and on occasions this causes a disgruntled OP to roll back a good edit (mostly new users). In the past I've caught this by looking through my edit history, but it would be nice to find out more reliably.
If this would raise a proper notification icon, that might be too noisy for most editors, hence my suggestion of a global tick-box to opt-in. If however it would be implemented simply as a profile tab, new "edit events" could appear as a count on that tab, just as new reputation points do. I would moderately prefer the latter, as it keeps the UI lean.
What do others think? Would other editors refer to this, or would it create noise that few people would use?
Based on feedback, I now envisage three possible approaches to this:
- Real top-bar notifications for subsequent edits, with a per-post opt-in system such as the one proposed by @jmac. This approach probably needs some way to specify notification settings, since "notify me of everything" will probably be too noisy for some.
- The same as above, but one setting for all posts. I'd mildly favour this over the previous option, since I can't imagine there would be strong demand for wanting to monitor some posts but not all. So, this is a bit simpler, but offers a basic UI to give the user some control.
A new tab in the profile page that lists all subsequent edits to all questions the user has edited. This would be very similar to the "revisions" tab at the moment - each edit appears in here and is expandable so it can be examined without much UI interruption. I favour this approach, to address the issues of complexity @James raises.
New edit events would appear as a tab indicator, rather than a top bar notification - just like the "8" indicator shown in my screenshot for the "responses" tab.
I would expect that each edit event would be separately reported, so two subsequent edits to a question would raise two events. One could argue for the presented diff to be between the current state of the post and the last time I edited it, but I think that's confusing - so would suggest that each diff is presented just as it is now in the Revisions tab.
Out of the three, I prefer the last one, but I think any of them would help me keep an eye on incorrect rollbacks. Thanks for your responses so far, and any more thoughts are very welcome.
