It eliminates a lot of the point of exploration to make that public, though. I think the sense of exploration / figuring stuff out / etc. is one draw to the explorer type, but so is having knowledge others don't and being able to show off the Magic Pants of Never-Before-Seen.

As an analogy, let's say I make it so you can't actually kill other players. You can beat the crap out of them, but they never drop below 1 hp no matter what. We don't really need killing and looting to make killers (which, really, is just Bartle's way of naming players that prefer player-vs-player direct competition) happy. I mean, you'll get into a PvP fight, and pretty soon one of those players will have been convulsing on the ground for a while and maybe the other guy is gushing blood. They both know who won, so we don't need to officiate that by having a death or give one an advantage by letting the winner loot the loser. Only players who want an advantage from being a killer should care -- real killers will be content to enjoy the fighting and winning as a process devoid of rewards.

Please tell me you wouldn't think that would be the dumbest change ever, but essentially, that's what you're asking us to do to another kind of player.
