Netflix came out today with a blog post saying that it will start rolling out (over the next few days) profile capability for their website, iPad, iPhone, PS3, Xbox, Apple TV. Wii and Android users will have to wait (“soon”). So instead of your Instant Queue being full of your toddler’s shows, you’ll be able to log in with a profile and see your own queue, recommendations,etc.
I feel this is a good first step. I’d like to see some sort of true parental controls, but I’m not going to quibble about it at the moment. I also didn’t see Roku mentioned, and that’s how I usually watch Netflix, so I’ll be keeping an eye out.
