What about providing a way for YC news to identify other users who potentially share the same interests as me? Basically, the set of links which I have upmodded provides YC news with a set of potential topics that I am interested in. Naively comparing this group of links that I have upmodded with that of another user may potentially provide a non-null intersection and show possible common interests; thus, that other user may be someone I am interested in collaborating with. Now that I think about it, another benefit of this is that more relevant news may be surfaced to me - if person X and person Y have a largely overlapping set of upmodded links, then perhaps the set (X-Y) may also be interesting to person Y, and vice versa. Perhaps this could be a way to deal with the perceived quality of news degrading as a site gets more popular as well, as it would allow the system to break off into smaller clusters of news items/people, where each item may be highly relevant to those who belong to the cluster. Sorry to ramble on like that - I don't expect (or necessarily want) such a complicated feature to be a part of the obviously minimal YC news site...just thought I'd bring it up for discussion. Edit: Used in combination with jwrecker's idea of having a more personal space, this could be a great startup idea - instead of YC News determining your set of links, it could simply be the set of links you post to your personal space :D
