Anyway, here goes the first one.
Back in the day (yes I am THAT old) when we had books and computer screens of only 80 columns by 25 rows, I've never lost my place in a long paragraph. However, now that we have wide displays with high resolution, texts can span for 15 inches! When I reach the end of a line and move my eyes back to the left of the screen to the beginning of the next line, I lose my position in the text! It'd take me a few seconds to get context back and find the right line. It's extremely annoying.
My solution? Bring back boustrophedon!

In the example above, the grey dotted arrows indicate the direction of reading. The first line of the text starts on the left and goes to the right, then continues immediately on the right and goes back to the left. You can imagine a farmer plowing a field with an ox, and when he gets to one end of the field, he turns his ox around and goes in the opposite direction to plow the next row of his field. This is in fact the meaning of boustrophedon, which means "turning of the ox" in Greek.

If we take this analogy of "ox turning" to ridiculous heights, then perhaps the most efficient kind of plowing (and writing) would to continuously turn in a circular surface. You might think this is contrived but I have seen verdant circular fields when flying over agricultural heartlands of America. Granted these fields are plowed and irrigated by machines, but the same logic of efficiency holds for writing as well. There is no interruption when the scribe arrives at the end of the line to move down one line. Instead he/she continuously turns the circular surface until he/she runs out of space.

I just noticed that this Blogger layout I chose is quite narrow. You probably read this whole post without losing your place in the text even once. I guess I've self-defeated my arguments to bring boustrophedon back. Oh well! Next time let's try to bring back logograms.
