Update, April 2014: I fully support Shog9's proposalShog9's proposal of adding the message where it belongs—in the actual editing form. This is less intrusive than displaying it as a notification, but it serves the same purpose. Can has?
Background
When you suggest an edit, the outcome of whether it was approved or rejected is buried deep within your profile. You have to navigate to Profile » Activity » Suggestions to find a list of your recent edits, but even those do not say anything about the outcome:
waffles♦ introduced this to "facilitate learning"to "facilitate learning", but what can I learn from this page? I have to manually click through the edits to see whether they were rejected or not. This is time-consuming or inefficient at best. There's also no learning involved at all, since there is no active feedback.
Feature request #1
If an edit was rejected, there should be a notification message displayed, linking to the page of the suggested edit (which states the reject reason).
This kind of feedback would improve the editing behavior, since otherwise, inappropriate suggestions might just continue.
Feature request #2
If the above is too intrusive, the messages in the profile's Activity section should be clearer, for example like this (compare against the first screenshot in the question):
This is similar to: Improving how suggested edits are displayed in your activity historyImproving how suggested edits are displayed in your activity history
Here's some more explanation:
Let's assume the case of a user suggesting lots of edits that are in some way harmful. Maybe they were too minor, like only changing keyboard shortcuts to use kbd markup instead of boldface.
Yes, we've already had this on Super User. Since it only takes one user to approve / reject there, some of these edits might even have been wrongfully accepted, others rejected. While this is a problem of its own, the user suggesting these edits will have a hard time even getting any kind of feedback.
They would never see the rejection messages because they're buried somewhere, unless they critically checked each suggestion in their profile. I doubt anybody would do this. Even more so, they might only look at their steadily climbing reputation, not really noticing a rejected edit.
Another case is users learning how to edit. How are we going to guide them if they're not told what they did wrong? They will just continue suggesting edits until somebody actually pings them in chat or comments somewhere.
Here's an example of a user who was completely unaware that he could see feedback somewhere in a dark corner of his profile, until he was banned from editing because he'd repeated the same mistake over and over.
