Recommended video filter
I mentioned this before, but could you offer a filter under the recommended videos to remove / filter out categories that a user doesn't want/ or like? Also make it reversible. For instance, clicking on the filter of x category, ask if you want to remove x category, yes, or no. yes removes all videos from x category, and never recommends a video from x category, makes the option reversible in case there's a video wrongfully categorized under x. Is that too much of a request?
