What about Null-Sec are you interested in?
I'm interested in my contributions to a corp (however small my contributions might be) making a tangible difference in the game. Holding sov, for instance. I suppose supporting some other type of effort would be appealing, but I'm new enough that I don't fully know what those even might be or how to contribute beyond "mine for the corp." I also like the idea of a higher level of risk and reward. High sec has its dangers, of course, but I suspect I'll be missing out on the fun of EVE if my risks are limited to war decs from griefers and freighter suicide ganks.
Low-sec would appeal to me, if that's what you're asking, though it seems a bit more chaotic. Edit: No, that's not what you're asking. To clarify: I like the idea of contributing to the political and economic strength of a corporation and/or alliance that can potentially expand but also potentially suffer real losses. I like a game where something is at stake.
Have you dabbled in industry beyond PI at all?
I have not. The level of SP investment required in order to make profits has scared me off, since I'm not entirely sure that I'd enjoy it or that I'd have the time/resources to do it successfully. It seems like having a POS is a necessity, no? I've enjoyed hauling however.
A bit more about where I could see myself going:
PVP ship: Recon ships appeal to me. Scout. Explore. Report hostiles to the big kids in the alliance/corp. Occasionally surface like a u-boat for some 1v1 if the set-up looks right.
Hauling: I'd like to eventually do freighters, jump freighters, and blockade runners. Especially the latter.
Industry: I have no idea what is fun or appealing or how to enjoy this aspect of the game. Perhaps I will find that I like it.
Mining: From all the advice I've read elsewhere, I should save this for when I'm a bittervet.
Note: Your corp looks awesome. If I sound like a potential recruit and the comms thing isn't a dealbreaker, I'll message you through the EVE mail system.
