Hartelijke Koninginnedag (sorry my Dutch is not so good, but hope that is somewhere near it)
I would second this proposal. I try to make my reviews a little more critical, however I tend to focus on the more positive things as I have made the effort to see the place.
It would also be interesting to see if any of the less well-known sites get high scores.
I guess there is the potential of this being abused and some sites being ranked extremely high due to local pride (Rotas Fort seems to attract an awful lot of uncritical reviews)
If anyone is interested I put my ratings on my profile
so you can have a look at them already if you like.
