Truth to tell, afternoon is not my favorite time of the day. Is it anyone's? Maybe the late riser prefers afternoon, but only because it is his or her morning — undoubtedly an "a.m.-centric" attitude!
The thing about an afternoon post, though, is that it says, by its very existence, that intellectual effort may be expended even when one thinks it's too late to bother. And, by extrapolation, that it's never too late to start/try/begin again.
