I find huge frustration in trying to get others into the F-plus. People are so conditioned by how radio and other Podcasts work, they sometimes aren't capable of appreciating what's being said.
For example, I once tried playing the Screech action hero fan-fiction episode for someone, and he listened for about 8 minutes, and then rolled his eyes and went, "Are they STILL talking about Screech?"
Even with my introduction to what it was, he still somehow couldn't absorb the idea that it was a piece being read and not say, Adam Carolla, choosing to talk about a subject for a few seconds. *shudders*
To be fair, it took me a few episodes to get into. I think the F-plus is extremely rewarding when you get to a place of understanding about just what's going on, but it takes more time than people often have the patience for.
