Facebook lays out events linearly in time, most recent on top, oldest on bottom. I don’t see it that way. Some of the best discussions happen when you dig up old photos and scribblings and say something about them. Besides that, time doesn’t look like a line to me. “Timeline.” Pfft. More like timefield.
