Cool, but the ultimate result - the related articles in that post - is not great. Suggested articles have barely anything to do with the topic. I think there should be minimal threshold (probably found empirically) for similarity and if no article reaches it, just don't show any.

Very true! The real limiting factor on the success of this feature is the lack of posts on my blog :D

Works much more effectively for posts about topics I've covered a lot, like SVG or web audio. Happy with the outcomes in general, though, as I can now apply to more content-rich projects.
