Facebook is now rolling out edit history across the board. What does that do exactly you might ask? Well, if you edit one of your comments it will keep a history of the changes for all to see. So if you are like me and quick to hit enter before you are done with thoughts then there will be a trail for everyone to look at. One thing I noticed was, if you delete a comment there is no history so might as well delete them and try again. That won’t help if you are trying to troll people though. Take a look at the screen shot below.
