14. A computer-implemented method of comprising: as implemented by one or more computing devices configured with specific executable instructions, computing feedback scores associated with pre-defined alternative segments of an individual unfinished work, the pre-defined alternative segments being alternative versions of a portion of the individual unfinished work, wherein each of the pre-defined alternative segments represents one of a beat, a scene or a chapter; generating a comparison of the computed feedback scores associated with the pre-defined alternative segments based at least in part on demographic criteria that divide commentators who provide feedback into groups; and providing data indicative of the comparison to a computing device to present to a user.

The computer-implemented method of claim 14 , wherein the groups comprise at least a first group and a second group, and wherein the comparison comprises comparing a first representation of a plurality of feedback scores associated with the first group of commentators and a second representation of a plurality of feedback scores associated with the second group of commentators.
