I have to say, I think they blew it with this one. Spinning DVD-by-mail off into a separate business might make sense, but I just don't get splitting the ratings/suggestions up by not integrating the services. Considering that one of Netflix's greatest strengths is the (very good) rating system this is a questionable decision, and I think they'll catch a lot of heat for it from the crowd that maintains accounts on both services.
Netflix has 8 years worth of ratings I've made, so it's gotten very good at suggesting me new movies.
Amazon is the only other company that has a longer history of what I buy and what I like, and they're making some decent inroads into streaming movies now too. As soon as Amazon beefs up their selection and gets streaming videos available on my Xbox 360, I'm going to find it hard to justify Netflix altogether.
