Actually, I'd venture the claim that I am more secluded over long times in my RP, than wormhole-dwellers:
I RP mostly, nowadays, in private channels, with select indviduals, where no one can possibly invade and where the most of the interaction is largely - I dare to say it - irrelevant for the cluster. Yesternight was the first time in years (I think) that I undocked to shoot at something - and then I was fashionably late. I'm a carebear nowadays and I don't shoot people. Even my times as forum-warrior are largely past me. So what? I still RP, every now and then.
Irrelevant has - just as relevant - two points of reference: X is (ir)relevant to Y. So, while my private RP might be vastly irelephant to most of the RPers in EVE, it is quite relevant to me and the other parties involved in the RP (I hope (; ). So, I think Anslo is quite right: All RP is relevant (to someone), else it wouldn't happen.
P.S.: And we really should respect that it is relevant to those people, instead of fenigrating it as 'irrelevant', because we don't have the angle to see it's relevance.
