Mmmh. If people want to vote yet make things go fast there are ways of course.
Might sound a bit heretical but it suffices to crank your judgement way high and skim the stories:
As soon as the style displeases you, the story fails to hook you or whatever, put the story aside.
Read through only the ones that genuinely works in all aspects, the ones you really want to read till the end, and note those.
Harsh criticism will help put the number of 1500 words shorts you have to read trough... Even if it'll let some on the side. One can always come back to discarded stories later.
If you have too many catching stories to read till the end I guess you're screwed, you're just on a too good forum :p
