Because I'm interested in collaborative filtering and progressive profiling and suchnot, I was drawn to this site

however, 155 ratings later, it still can't predict what movies I like. I suspect part fo the problem is they ask you to say whether or not you think it was a good movie, rather than "did you like it"... two different things. I'm sure we can all think of movies we saw, had to admit that it was a good movie but a toruous 2 hours. i've been avoiding "Boys Don't Cry" for just that reason. I also suspect they are missing the important option"would not see it if you paid me" as opposed to merely "not seen".
I also managed to thwart emode.com... The What Breed of Dog Are You? test said I was a happy go lucky pug (?!?!) Maybe i'm just difficult, or maybe the fine art of predicting what people like has a long way to go. (or maybe I'm a pug? Argh!)
