Against it. I love reading up on the various happenings of Sirius. I don't care if they effect me or not, the politics and role play make it entertaining to be in the know.
How then would you suggest we isolate knowledge gained from one player's character from another of his characters? For instance, what if I have both an Outcast and a Corsair? I'd be privy to knowledge that you would suggest is restricted by necessity. The issue can never be dealt with beyond self control. And I believe that this is possible. I agree with Kanga, this shouldn't be difficult.
It does suck when others metagame. It can ruin situations and all that, I just don't feel that this is the solution to that problem. I think that your suggesting that we don't care because we don't agree with your ideas is drawing false conclusions.
