We have been working on a recommended saves system for TPTNet server. In general it does this from tracking your save viewing history (creepy). It will then find certain similarities between the saves via super-secret methods and create a list of saves related your your view/vote history.

It would do such a thing on a live basis as that's how it does the front page right now on TPTNet. Another thing I should mention is that by default the server does log view history in order to count the unique views instead of a person double viewing it. Last, such a system will include an opt-out feature and those saves recommended to you will be highlighted in colour.
