For my part, I'd be interested in contributing as well as perusing if the powers-that-be decide it's worthwhile as @Stevebrot mentioned. I think that it is.
I was in fact considering this just a few days back - the PF review section is a phenomenal resource for Pentax related photo equipement and lenses of every sort. Nothing really exists (that I am aware of) with as much width and breadth for any other maker. Information is pretty disparate for film equipement especially. I've wished that such a well of knowledge/opinion was around for, in particular, Konica cameras insofar as I'm concerned lately. It'd take quite a while to reach anything approaching the scale of the Pentax reviews section, but it'd certainly be valuable in general, if not necessarily at PF.

Originally posted by ChrisPlatt Very cool indeed, though it can't take into account what an ongoing and living, web-located review section can... namely how each piece of equipment ages and values/devalues over extended time, and is limited in scope from the onset (even one so all-encompassing as that!).
