Indeed, that seems to be the hardest problem right now...

If we can't think of anything better, one possibility would be to simply 
ignore this problem for now, and see what happens. Circle is vulnerable to 
intelligent attackers anyway...

Umm, I was thinking of a more concrete algorithm for aggregating votes, 
really... the mechanics of getting votes from A to B are easy. (My initial 
thought was to simply have them in a file with a standard name, shared like 
any other file, which would have the advantage that it could be retro-fitted 
to *any* file-sharing program, not just circle. The other methods proposed 
would work just as well, though.)

The part of the aggregation method that I have least thought through is the 
bit where I say "the people who tend to agree with you on the rankings". How 
is this measured? Given two people's votes, how do you determine whether 
their tastes are similar?

(Note: actually, the taste comparison would be on a per-category basis, so one 
would rank each of one's own categories against each of everyone else's.)
