Temporal Preference Filtering
A typical "in-the-shower" thought for music playlists: we already have personal and collaborative filters to rate tracks in our music collections and propel popular tracks to the top of (suggested) playlists. Both are static filtering mechanisms though, ignoring the dynamics of chaning tastes over time. I think it would be worthwhile to add a temporal component to the gathered use/preference data and to subsequently segment search data into temporal categories.
An example: Maybe three years ago I liked ska a lot, but now my tastes have changed to electronic folk pop. A rating mechanism should take this change into account, offer me mainly e.f.p. tracks at the moment, but allow me to take a look back at my past preferences along with related material I liked at the time. Sentimental reminiscing will be some much easier. hah.
