I find myself editing my comments a lot, mostly fixing minor errors. Seeing a large quantity of comments that have the same errors, other users suffer from the same issue.
Soometimes there's an extra space in the sentence, or an extra "o" in a word . Occasionally will I skip a small word or up swapping two words around. Or maybe I find that my comments has stupid pluralization error.
Whatever the error is, it's beyond minor. By the time the writer returns from where-ever and realizes that they have to make such a minor fix, though, it already says "4 mins ago" and time is running out! To hover on the comment, click edit, make the change, and hit Save edits probably takes no longer than 4-6 seconds. But lo, in that mere blink of an eye, it's already 5 mins ago!
I propose that we extend the window for editing comments by 8 seconds. It's too short for editors to make substantial changes to the comment. Because most people don't bother with spans of time between 5 and 10 seconds, no one will notice that the change was made ever so slightly later than 5 minutes. And yet, for those people who rightfully notice just in time that they need to make a minor fix, it's a welcome window to accomplish their task and avoid everlasting SHAME!
