I use namingschemes.com but it has very few games in it, and it's focused on networking naming schemes :)
A wiki is probably what you want. I was going to suggest tvtropes, which is great for, say, a list of every superhero with X-ray vision, or every work of fiction containing dwarves, but I’m not sure that fits what you want.
