Or at a minimum, surround the bottom foot or so of the post in the hole
with gravel- cover the bottom of the hole with gravel, put the post in,
pour in some more gravel, and only then add concrete. The wood should
never sit in a concrete pocket- that will rot it off at a young age. And
yes, 'coning' the top so water doesn't pond against the wood is also a
good idea.
It all depend how long you want the fence to last.
