Sebastian:
I usually don't respond by continuing with further comments, since I don't have the time to linger on a particular story
This is a really important point.
The writer has invested hours - perhaps between 4hrs and 8hrs on that story.
The reader has invested minutes - perhaps between 4mins and 8mins.
It's easy to make the comment, which can hurt like a barb, based on minimal investment.
The author, IMHO, should ignore it and move on. (Easier said than done for those of us with thin skins)
