I can receive over 30 messages a day, from various sources, mostly lists.
I daresay many receive very much more. I cannot possibly keep them all -
relative irrelevance to me, or indecipherability, may be just two reasons
for deleting them. This, as I understand it, goes with the territory.

I see no benefit in postings which complain about postings - it can
degenerate so quickly, and, once started, is so difficult to finish.
