OK, so I edited a question in Programmers. The poster had misspelled a word, and I corrected it. I do this all the time in Stack Exchange. And... My correction was fewer than six character (because the error was fewer than six characters), and my Edit Summary ("typo") was fewer than ten. To me, that's a good and appropriate edit. But I was encouraged to lengthen the edit, and required to lengthen the summary - that's dumb.
Then, because I don't yet have edit privileges (or because I wasn't logged in), I got this message:
Thanks for your edit! This edit will only be visible to you until it is peer reviewed.
Actually (assuming it passes muster), my edit will be visible to me forevermore. It will be visible ONLY TO ME until it is peer reviewed.
