What do you do when you've made a comment, but much later realize it wasn't such a good idea after all? If it was someone else's comment, you'd comment on it, addressing whoever it was. So if it's your comment, I guess you address yourself.
Seems a bit silly, but makes logical sense. So it got me thinking, "Hey, there should be a badge for that!" (Badges are like apps in this sense.) I'm not sure what it would be called, maybe split personality - something not too serious, in any case. :-)
