What I said earlier about "wrong side of town" - I'm of the opinion that there are people who like to interact in-game and those who like to interact on the forum, with not too much crossoverDo you ever asked a player what he is interested in or do you automaticly asume no one doesn't fit your playstyle? When I meet someone and I am up for that, I ask that person via in-game chat what he is doing right now and if he wants to wing up. Sadly most people don't respond but if, it can be a lot of fun and making new friends as I described with the Guardian site. I'll never understand, why people want to play multiplayer games (Elite or any other game) alone, it's always more fun with more players.

But that aside, the game is clearly designed to have the play mode option. It gives it a bit of a split personality and waters down its MMO credentials, but it is by design. The real question you should be asking is "should there be features in the game that support engagement in open mode?" which I think is a resounding yes, because for many of us, it's a unique and addictive thing when two sides play off against each other in good faith, in direct conflict. Or when co-op play emerges spontaneously. You might say powerplay is the perfect candidate on both of these counts, and commence the open-only PP merry go around. And I might agree, but why stop there? Why not have exclusive play that caters for all preferences? What if there was solo-only gameplay that was so cool (and made sense to be solo-only) that it made me, as a career open player, want to log into solo to do it (and not just as a chore for some form of grind)?
Can we have our cake and eat it? Can the split personality of the game be embraced rather than devs closing their eyes and going "la la la la la" about it? A couple of CMs have uttered the words "open" and "powerplay" in the same sentence in recent months - perhaps the hands are unclamping from their ears at least.
As to what you can do, engage on the forums to represent your outlook, sure, but moreover get the word out on what everyone is missing by assuming open is a dragon-infested maelstrom of fun-kill.
