While I'm glad they finally implemented Netflix profiles, my account is jumbled with all sorts of stuff watched by people in my household and there is no way to reassign those views (as far as I know) under the new appropriate accounts. This makes my profile a jumble mess.
The only alternative is to start a new profile for myself as well and abandon the primary account and start fresh for everyone to ensure recommendations are all proper.
Yea - they didn't quite think it through but I can't imagine the work to let people fix their history to be too big of a problem. Especially if they limit it to web interface only.
