Actually, a DiF wiki could be really useful. And you've got tons of people to help edit entries. The work wouldn't be all that different from Project Halp.
You would have a page for each episode, a list of participants, maybe a few bullet points about discussions had in the episode, and then a quotations section. Maybe somewhere down the line you could introduce episode transcripts, so that I could search and find in which episode a certain movie was mentioned, or a person was brought up.
I mean, it's a massive undertaking, considering the sheer volume of DiF content. But I think it would be really cool.
