The Golden Age...

[byslantedlight.livejournal.com]

I have an idle question, arising slightly from recent ProsLit threads, and slightly from thinking about the Old Guard question of a few days ago...

When people talk about the "Golden Age" of Pros fandom, when in particular are they meaning? I'm never sure if this is one of those times that differs for everyone, or if there's a more generally accepted "period"? And what would constitute a "golden age"? Quantity of writing/activity? Quality? Something else?

I shan't post this to ProsLit as well, because I know it gets cross-listed there automatically, but it's really for both groups. I'm very curious...
