I think the biggest problem with this idea is that everyone has different tastes and likes. This would be a boring place if we all had the same exact opinions of anime. Making lists of what is good by opinion will conform some new users to all like the same thing. But if you think about it, just about any anime will be on the list eventually... so it's really pointless.
*EDIT (reply to below)* If it's for new user's... well there's nothing that can be done about stopping them. The only thing that can be changed is the new users themselves to start figuring out what is good for themselves!
