Very interesting to see the data binned out like this!

The "spikes" make sense to me as correlation to various events, fannish and global (like, I'm sure they correlate to changes in LJ and Tumblr that drove people elsewhere, to a significant degree).

There does seem to be a slight general downward trend if you look past the spikes, which I'm not sure what to make of... Further fragmentation of fandom? Fandom moving away from these kinds of spaces and towards Discord. Hm!
