You might have already noticed that when you look at individual episodes, there’s a list of similar posts at the bottom. I had this feature once before and now I have no recollection whatsoever why I turned it off. Maybe I’ll relearn something shortly.
So what the thing does is compare the text, titles, categories, tags, and whatnot of the episodes and comes up with the ones that match the best. The whole thing is tunable, for those inclined to do things right; I just chose some numbers that seemed reasonable. So far, I’d have to say that the code really likes episodes with exclamation points in the titles. I’m good with that.
I just spent about twenty minutes cruising through history, following one episode to the next (ostensibly) related one. It was pretty fun for me, but probably in a you-had-to-be-there way. To be honest, I think this feature is mostly for my entertainment. But you can use it too, if you want.
