I was thinking about the whole "fandom moves on to something else" thing and it made me think about my annual picnic. Every year, I have a big picnic in early November and invite a bunch of people. I rent out a pavilion at a local lake, have people bring food that I grill for them if they want, have some games for the kids in the group, and just generally hang out.
Now, the way this goes is that I have everyone show up around 4:30pm. People show up, it's a big crowd, it's pretty warm out because the sun is still up and the mingling is great. People eat, share food, the kids run around in the trees and check out the lake, and we all just generally enjoy ourselves and catch up. Then the sun starts to go down.
People start getting under the pavilion, it starts getting a little chilly, and maybe those with really young kids start to pack up and say good-bye. This is usually when I light up the fire in the pavilion's fireplace and people will begin gathering around there. I let the grill burn down and sit down with everyone as everything gets a bit more mellow. Maybe we make s'mores or have cookies or something but this is usually were you start having more people say their good-byes and head out. That's how it goes for the next couple of hours, little dribbles of people winding up and heading on home until it's 9:30 at night and there's just a few people left in the pavilion in the woods sitting around a little fireplace quietly talking.
You know what? That's the best time at these things. Some years we'll be out there until almost midnight, just chatting quietly and staring into the coals. You learn things about people then, you hear interesting things, and you just feel closer.
So what does this have to do with fandom and moving on? Well, I see it like this. The show is still on, that's the early part of the day. Plenty of people around, lots of activity where art gets made, headcanons and meta fly fast and furious, and tons of fic gets written. Then the show ends, people are still creating but a few peel away, they have other things they have to do or just aren't interested in sticking around. Slowly but surely it goes until it's just a few people left.
That's when the interesting things really start coming out. You still have the other stuff but you start to get off the wall headcanons and wild meta, you get odd art, you get fic the person finally decided to write, and it's good. And hey, every once in a while, someone shows up late and you grab some food out of the cooler for them and warm up a burger for them over the coals while others grab a chair for them and you get them up to speed on the conversation and maybe show them some pictures from earlier in the night and they get to have some of that glow from earlier even if they missed the original.
That's fandom to me. As long as a person is still sitting around that fireplace late into the night, ready to chat, the fandom is never dead.
