Producers are a huge piece of the puzzle to unlock. They tend to stick in similar areas of music, so odds are, you will like the other stuff they work on. Great point.
Ironically, very little of the conversation in this thread is discussing the actual link, which is a mailing list of human-reviewed releases.
Most of the comments appear to be about the best algorithmic recommendation engine. I've used them all and still think it doesn't compare to the experience of human-curated music. Even a 1 paragraph review of the record tells me more than a "You might also like [___]" message.
