How hard is it to program a bot like this to default to "part one" when doing a brute force "people who like X also like Y" and exclude obvious recommendations like "people who rented season 6 also rented Season 7"? I realize Netflix gets the same amount of money from me each month whether I have 50 or 80 movies in my queue, but if they're actually trying to build an intelligent recommendation agent, these are major "duh" obstacles.
Also I'd be remiss as a curmudgeon if I didn't single out half.com, which removes things from my wish list once I buy them (good!) and then recommends these same titles to me as "people with similar tastes also enjoy..." months later (dumb!). Also notable is the habit of recommending music to me that I've sold on half.com, ie: "People with your tastes bought this, didn't like it, sold it, and then were persuaded by a bot to acquire it again".
