Both, actually! I didn't so much move on from SPN as drop out, or, shall we say I'm taking a sabbatical for my health. P: I'd already drifted a little during the hiatus between 8 and 9, then when 9 started airing there were a lot of shenanigans I felt were bad in a small space of time so I swore it off completely for a while. And now I'm kind of drifting back, but read enough goodawesomelovely fan stuffs that returning to canon is jarring, you know?
(*Edit, also I followed the migration over to Tumblr a while ago, but I'm drifting back to LJ now a little too. It's funny how stuff works in cycles sometimes.)
Any other fandom that you chose to do another timeline for would be honoured by it, I'm sure. :)
