Limitations of implicit recommendation

Implicite recommendation have a lot of advantages ... mainly it's effortless !
But  it alsa have many problems. The list is quite long but it could be sum up with "making mistakes".
That's something user would not accept especially if it's a mistake that a five year old boy wouldn't have made. It's a bit like, in the old days, altavista not finding its own website when asked.

This is just an example from Duke about amazon.com. I told you a few days ago that he is making a huge digging on the recommendation. Take a look at the comment on flickr from where the photo is originated.

here is another problem @ amazon. it's from Nicholas Carr and it's about tagging.

Imdb has a pretty effective way to organize tagging in a tree like system. But they have a lot of sex related items and are using many tag in that area ... generating problems @ amazon.

Another good article on the subject is from librarything and about the really small amount of tag amazon has generated from its users.
