being a part of things like Mulder & Scully's Bogus Journey (thank-you very much Wayback Machine)
the long-defunct star wars rpg the Bounty Hunters' Guild
in short: being a part of a like-minded community. Sure, I'm a member of a few forums here and there but they are largely non-specific beyond one common thing (i.e. Notebook in Hand's common theme is Creativity - but that is a very broad connecting theme. Not complaining a lot, mind you, it's a fun community!). However I don't think there's anything out there right now that I can jump into. No fandom that I'd like to join.
Perhaps though, that might change if I can be on the ground floor of that Blood & Chrome series comes out, I can get into that. Although to be honest, I'd rather it be something like a new Star Trek or Star Wars series, or something. As much as I like the Battlestar Galactica franchise, it feels like something with a concrete end, rather than something open* like those other two franchises (or even Stargate - and I tried and horribly failed to get into THAT community when Universe was launching).
I really didn't have a grand point to make in this post, except that I think my lack of a community to participate in amongst peers is leading me to try and fill that void by becoming Internet-Famous; I'm constantly trying to think of cool ideas to pull off after seeing something particularly neat that someone else has done. And then I remember I need actual artistic skills to become "Internet-Famous". I'd much prefer being the second kind of "Internet-Famous":
Obscure around the globe, but at least well-liked by members of a like-minded community. Is that so much to ask?
