Disclaimer: I've only been watching the show for the past two years (though I haven't kept up with this season) and I don't think I follow anyone on Tumblr who isn't at least peripherally interested in the show, even if they've stopped watching it. That and I don't really go digging through the tags (which is probably how I missed Andy's involvement in the fandom before this).

But I will say this for what I've observed in my little corner of Tumblr/SPN fandom: Everything about this whole season has seemed to move fast, both in the series and the fandom. I mean it started late and immediately jumped into killing every character who'd managed to escape it in previous seasons, wrote out one of their most popular recurring characters, and so on. I don't think I haven't seen one person still actively watching it who hasn't talked about the finale at least once in the past couple of months despite not having any idea what's going to happen.

But yeah, I guess the other thing I've noticed about SPN fandom is that big fandom events don't tend to do very well, if they ever get off the ground to begin with, if they're not explicitly backed by a corporation, as I'm led to believe most, if not all of the SPN conventions are.

The whole culture of SPN fandom is just really weird. Which is maybe why he didn't gain as much traction there as he has in the past.
