I have noticed that undo is being used far too much lately. Many times, no reason is given and the edit is undone again with an edit summary say "Why? This edit was good." Most of the time, they are correct and this is becoming more and more common. People seem to be using undo for no good reason other than to use undo. I am thinking something needs to be done about this, but I don't think I should take it to the forums to be voted on before we get some ideas out. Before anyone says anything, I believe that requiring and edit summary for every edit would be too bothersome to enforce and new users wouldn't follow it.
PS My 10,000th edit.
