Am I right? If so, one response is that this funky behavior is
mostly a
function of the particular data you have constructed.
Actually, I get all recs from the new user. If I have a less overlap
between the 'philes, then some of the other users start to creep in.
So, I think I see what is going on and it makes sense.
Agreed, the problem is due to the construction of the data, but I
think the approach as a whole is interesting. It might behoove me to
have the 'philes rate some other data, too, just to throw more in the
mix.
Thx,
