This is a very good initiative really, and one I believe will benefit the gambling newbies amongst us more regardless of my personal thought that such a list won't really be important for those of us who already know our way around here.

But then, my thought or something that came to my mind while reading your post is that, if you really want sure of the best casinos on the list at all time, then you have to figure our a way through which the bitcointalk community can vote on this casinos, a casino can only make it to the list of it manages to get a fixed number of votes from different users on this forum.

It makes no sense to me for you to add a casino to the list simply because one of two persons suggested it to be added, as a matter of fact, anyone can create a fake casino and suggest it to be added to the list, and if it ended up getting on the list, many will trust it and eventually become victims to scam.
Think about this, and incase you don't understand what I mean, I could explain a bit further.
