1) If I understand correctly the first slider ranks greater similarity in commenting on the same threads the farther left you go and similar word choice the farther right you go. Why not make this two separate sliders? 2) For each of the matches could you show some of the data used to compute the matches... e.g., for semantic matches, show the top X (maybe five?) common words or phrases you matched on. For threads, show the parent or OP of the five most recent threads... something like that. 3) Really neat. I like this. It's quick too. How did you do it? Did you replicate the entire HN database? Third suggestion: post the source or just post an explanation of how it works.
