A:

I'd like to nominate רבות מחשבות's answer to the question Source and etymology of כפירה kefirah 'heresy'. His answer is very concise and well sourced, getting straight to the point and answering the exact question of the OP.

A:

I was originally skeptical of self-nominations but the community seems to deal kindly with them. So allow me to nominate my answer to Above ground burial which took quite some research to answer a question I asked myself many times.
That particular question was bumped up to the homepage the same day that I drove alongside such a cemetery pushing me to try and answer it.

A:

mbloch's answer to Can 'cruelty to animals' render an animal not kosher? picked up a nearly-year-old complex, unanswered question and gave it a very well-researched and well-written answer, including helpful citations of contemporary responsa and literature. The question touched on halacha, ethics, economics, and industry practices, and the answer addressed all of these.
