Rethinking this, there might be another aspect to people disliking individualized (versus character-type) muses- they're so damn personal. Looking at it that way... it is a kind of squick to read strangers going into a lot of detail about what personally inspires them; it seems too intimate to me. On some level, a muse will be a reflection/distortion of some essential aspect of yourself.
As ever, though, if you're squicked by it, why read it? Which sometimes seems like the fundamental question of the internet.
