Oh, interesting. From your description it sounds like you track a progression -- someone you meet via fandom becomes a fandom friend, and then may over time become a RL friend. Whereas I generally use the term "fandom friend" to describe any friendship with someone who is fannish and who I interact with in a fannish context, which means that the vast majority of my friendships are of both the "RL" and "fandom" variety.

So, f'rinstance, I consider yarngeek and oliviacirce to be "fandom friends" because our friendships started through fandom and we regularly track one another's fandoms, rec each other new fandoms, etc. But they're also the two people I depend on most for sorting through RL issues. It's further complicated by the fact that any given communication I have with my close fannish friends tends to blur back and forth between discussion of RL and fandom without a clear dividing line between the two, and that we often use fandom frames in our discussion of RL issues.
