Being an old sort, I've been doing the RP thing for a very, very long time. Basic D&D sort of old. That being said...
That we're even having this conversation, puts our little community leagues above a LOT of other games' communities. We do a very good job of avoiding blatant SF and Space Opera names and conventions. We don't have to deal with the player who is dating the GM and gets the Pollyanna (Sookie) character with the uber-wonky powers. Game mechanics keep us from having to suffer the "power-gamer" and the "rules lawyer."
For my RP, I try very, very hard to tell a story or enhance a story that is being told. The rules I keep for myself are avoid tropes (though I realize every character and situation is a trope:
http://tvtropes.org/) and keep it logical. This is SF, and while we don't all need multiple doctorates, if I can keep my character from walking around on top of the station without a EVA suit, I'm ahead of the curve. CCP gave us a good universe to play around in. So yes, it's a bit silly to be running down the corridors of your ship to put out a fire when you're supposed to be in a capsule and can just remotely open a hatch. Everyone starts somewhere. We're the people that help the new people work out the details.
CCP has been taking a lot of cues from us recently. So as long as we're good storytellers, being good RPers will just come naturally. So don't be too harsh when "Capt JamieKirk" logs on and tells you he's secretly a spy from the Drone Collective. Gently point to the OOC resources and help him along. Then if that doesn't work, space the fucker.
