This is really well done! I would recommend putting the defaults back in and playing around with and finding a good value for "remove connections that have less than" using a number based on a percentage of the posts in sub instead of an arbitrary 8 connections. For example, remove connections from /r/programming to subs that are cross referenced from /r/programming less than 5% of the time. Again, very nice!
