Another fun day a year or two ago on Tumblr involved the old classic top-posting vs bottom-posting debate. I don't remember the details precisely, but it was something like this: They switched the default from one to the other one day, so that mid day your replies started being top posted. And so you got that wonderful mix of top and bottom posting. Then they fixed it, and so you could have a thread that had just top posting in the middle. Neato. Thanks Tumblr.
