The only threads that really make any sense to deleted are the ones asking if ABC company is down or slow tonight and it is just an off night or upgrade, etc. and a day or two later everything is functioning normally. Otherwise i do think it is likely that the questions and comments are useful to others. I really dislike it when the OP is deleted, but tons of comments remain. In those cases, I wish the poster would either leave it, state that they realized it was and ICA violation or admit they were ranting unnecessarily.
