have you tried it? It doesn't recommend anything new!
I reviewed The Filter yesterday for GoMo News. Basically it didn't recommended me anything that I hadn't already told it I liked!!!!!!
I went through telling the system more than it apparently needed to know, by selecting more artists than it asks for, I imported my Last FM preferences (40,000 tracks played), an extra way for the system to apparently recommend new music. I even downloaded the widget to intergrate into iTunes...and guess what?
I told it I like Air..It recommends Air
I told it I like Good Charlotte ..It recommends Good Charlotte
I told it....yada yada yada...
What was The FIlter doing..ringing up my best freinds and asking them!! Is that how Boolean mathematics works :-)
