Mr. Black, I enjoyed your editorial on "Postscripts" and the dilemma of titling all the letters that will be printed in the Chron's online edition ["Page Two," Aug. 15]. (Shame on you, by the way, for that callous and uncalled-for title ["Have You Ever Read Our Paper?"]. Really! What were you thinking?!) I would offer the suggestion that letters could be sorted by subject matter, with very straightforward titles for the categories, and a miscellaneous section. You'd only have to rack your brain for titles for the published edition.
