Whilst it's very true that fog has been in the mod for some time now, as VJ above as said, he, and other administrators I am sure, have previously adjusted the values to suit them / their communities in the past. So many players haven't experienced constant fog at the levels they are currently seeing in build 1.8.5. My opinion is that weather is an integral part of Dayz, and fog is weather, I like a full and varied weather system, however currently in build 1.8.5 I have experienced fog, usually dense, reducing visibility to 300m the majority of the time, and giving a maximum visibility of around 800m, but the fog is always there. The only variation we get now, is rain / thunderstorms, never sunshine in my experience. TLDR; I feel that fog needs to be in the game, however the volume of fog, and the ammount of time weather in-game is "foggy" is too great, and could do with being reduced, to allow for more variation.
