However one of the features I most miss is a “serendipity factor” dial.
A basic concept in information filtering is the degree of serendipity of content selection. Do you want a highly predictable stream, or do you want to be very surprised sometimes?
I vary in how much I want the serendipity dial cranked up.
It would be totally awesome if Last.FM were to introduce a serendipity factor dial.
How about it guys?
