Check out this forum where people do what we do, but with real locations!
Much of the discussion is about how to best represent maps using various forms of software. I've only just begun browsing through the site, but it has a lot of information and help on software use and map design.
I think I posted a link to this forum a few weeks back when someone was asking about how much Cartographers get paid...
I have an account over there and I posted a hello and some feedback to another guys illustrative map...I have this site in my sig over there too, so ya never know.
Fantastic site. I've added it as a Favorite on my browser. I might find myself spending a lot of time there. Though, not to detract from my time here, of course.
