I'm still not sure what's the difference between a thread and a permathread.

Is one aspect of it that permathreads are just for information but not discussion?

For example, I have questions about the instruments and the location of the festival that McGrath provided links to.

If this video were in a Mudcat permalink, what would be the appropriate place to ask those questions or make other comments?

[Btw, thanks Murray and McGrath for those posting those sample links!]
