For almost all subjects X, an X festival is an excuse to drink beer, hang out, and do silly X-themed stuff.
This should not be taken to mean that it has nothing to do with X, or that it adds no value toward it. What you're really getting out of it is an opportunity to meet other people who're into the subject, or at least well-disposed enough to show up to a festival advertised as such.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
