In my opinion, if the lists are revealed three cards at a time, the fact that they are lists is going to get lost, at least for some. Also, as Fabian says, these lists are based on what the community as a whole believes, so we need to hear the opinion of everyone who wants to contribute (and that includes you, I am certainly not saying your comments are not relevant). However, the community as a whole can't really contribute their opinions on the list when we only know where three cards are.
I feel that it would be best the release the lists one at a time as complete entities. Maybe one per week or more often depending on how long discussion lasts. That way, everybody can see the a whole list at the same time and discuss it together. Of course, you can give your comments too however you originally planned to, just list by list rather than 3 cards by 3 cards.
That's what I think would be best, anyway. It's your list so it's up to you.
