I like the Roku Channel, but I will not be using it much. The really annoying "Because You Watched" recommendations can be somewhat embarrassing if you have watched something adult, or controversial in nature. Everyone who uses your Roku can see what you have watched. It makes me uncomfortable.
Roku actually needs to add a Reset to this feature. The AI is not very good at suggestions anyway.
At least you don't have the worries of many Tivo users.
