Jekyll has the ability to use latent semantic indexing (LSI) to determine related posts within your blog. I wanted that same functionality in Middleman, so I wrote an extension for Middleman, middleman-related-articles. I don’t have enough posts for it to make any difference for me right now, but I’ll be interested in seeing how it behaves as this blog grows. I’m also really interested in feedback from any other users. After I get a little more confidence using this extension myself (and maybe after this issue in rb-gsl gets resolved) I’ll probably try and advertise it a bit to Middleman users.
