I for one think that having a "best of" posts or some sort of reference/archive section on PF would be very powerful.

The thing that differentiates PF from other gun forums is that it is dedicated primarily to the serious use of the handgun as a weapon, as opposed to primarily being about collecting and owning weapons.
To those of us that have been here for a long time we've had the benefit of reading the refined thoughts and experiences of SME's who have spent countless hours working out the how, what, and why of serious handgun shooting. Most of the threads that contain those thoughts and experiences are nowhere near the front page of any of the subforums of PF, meaning that someone who is just now discovering this site has no way of knowing those posts exist, and will never gain that knowledge.
This is just the natural progression of those sort of conversations.... We have already talked about the really important and fundamental things a LOT, such that the fundamental things have already been said, so there doesn't seem to be a need to say them again.
The things that there are left to really talk about are, for the most part, topics of lesser importance such as the finer details of gear choice or more obscure/specialized topics.
