That sounds like awful lot of work for very little gain.

Which is exactly the difference between market that is dominated by people like you and the one that does not. I don't need to go out of way to explore to find tv series I will like. That market is clearly dominated by people like me.

That is how humans behave instinctively. It isn't work. It just happens. The same will happen to your TV series. At some point, you'll like different stuff.

It also isn't "little gain" - it's the most efficient approach to the multi-armed bandit problem. Other approaches are less efficient.
