Facebookers write for the next few minutes or hours. Newspapermen write for the next few days. Corporate entertainers (consultants, economists, and all sorts of “thought leaders”) write for the next few months or, more rarely, years. A minority of academics write for the next decade or beyond. Men of letters write for time and for memory.
Life is short. The shorter the half-life of the information, the lower the signal-to-noise ratio, the less time you should spend on it.
