Netflix Profiles are here, finally a way to have your viewing habits separated from other family members. Up to 5 profiles can be created, but these don't necessarily need to be family members either. For example you could create one for Sci-Fi, or Comedy etc and then instant queue the appropriate movies under those categories. 

Seems to be only working on the PS3 and the website at the moment, with more devices getting it soon apparently. But if you set up the profiles on the PS3 and then going into the website and clicking by your name it will bring up the list of profile names you created.

One option I would like to see is to password protect the profiles.  Especially if you were to watch content not suitable for children.
