Have you experienced that your answers are removed by mods because they does not live up to standards? This is only supposed to happen if the answer is outright spam or offensive or totally unhelpful. Otherwise they are just downvoted.
Can you provide a link to an answer by you which was unjustly moderated? I can vote to re-open it.
I simply do not have time to ensure my responses are in "tight enough" shape to stand up to what is quite honestly overzealous moderation for the pure sake of moderation.
TLDR: The community focus on the "meta" aspects of SO: How we ask questions, Answer etc - has killed it for me.
