I don't think so, actually. Admittedly, my roommate has posted before with comparisons of hit counts and comments, so I think her flist is more susceptible for guilt over the realization that the poll is a response to people reading and not commenting. I think that would be variable, based on flist composition and relationship. Otherwise, I think most fics getting comments would get solids "like" but not "love", which would be a contrast to the way comments are written, generally leaving the impression that a fic gives orgasms and cures cancer. If it did leave to people explaining why they didn't give perfect scores... well, that could only be an improvement, I think, because then you are getting concrit.
