Looks like a good idea if you are looking for specific cosplays. Looking on the Facebook link, I read a lot of comments that say "I want to do this..." or just discussions about the series but didn't see anyone tag themselves in the pictures (could be hidden or PM'd the poster).
I do have a couple of questions about this comment:

How would you frame your post? Only friends and/or good cosplay need apply? How would a cosplayer know if they met the "good" cosplay threshold and if they didn't how would you tell them? I'm not trying to be nasty just some questions that popped into my head when I read this.
