* I think age may be a big problem - if a user posts in ''i'' before ''j'' exists, then they couldn't have posted in ''j'' first
* I think age may be a big problem - if a user posts in ''i'' before ''j'' exists, then they couldn't have posted in ''j'' first
* I thought it was at first, but this is not quite the same as testing if <math>P(i|j) > P(j|i)</math>. The downside of that approach is that pathways can get diluted in the case where a subreddit acts as a gateway to multiple other subreddits. I think that my new approach is closer to the intuition I wanted.

** I also only look at the immediately subsequent subreddit and only the first time someone posts in a given subredit. This is not obviously the best way but controls somewhat for heterogeneity in activity levels.
* This produces a lot of edges! I would like to figure out a good way to prune them - the simplest is to keep limiting by the proportion of the posterior < .5, but maybe there are some other ways?
