Reposting Questions? was really good reading to my question,
but there's still some drawbacks -- users still must
count on calculating a probability of an answer (not holidays, not weekends,
just bad current carma on perlmonks due to a person that irritated anyone,
like me now).
I think this should be improved somehow, but have no 100% solution.
reposting questions, even with pointing to a past questions with many politeness,
could not work forever, you'll make readers angry after 3rd post.
And no, I'm not complaining about questions that could not
be easily answered.
I think there's distionction between
"zombie" questions and "dead" questions, which should not be answered due
to some reasons.
