That rang true for me. I have extended series and repeated themes from the earlier years of this blog which I have thought worth a little something. I have sought ways to go back and collect them, repackage them, or revisit them. I now think the distance is too great, even after only few years. A year ago I would have thought that one did not really understand what is going on here without that background. I no longer agree with that. Blogging is more like old newspaper columns (or Letters To The Editor) than like collections of essays. Only a few columnists get their Best Of's arranged between covers, and even then, all the other columns just slip away. Ephemeral does not mean "unimportant or worthless," though it has taken on that secondary understanding. It means "for the day only." Facebook and Twitter are even more ephemeral, of course, but that is their nature, and things should be what they are.
I might look things over and see if my understandings have changed in any way, and write up the changes if they seem important. But they are what they are.
