Yesterday Youtube switched me over to this model. On the home page now it primarily recommends subscribing to "topics" rather than individual channels. For example, I regularly look up recipes on Youtube, so it has suggested I subscribe to the "cooking" topic as opposed to Alton Brown, Tasty, etc.

I have two "modes" though which I use Youtube. The first is searching for the answer to a specific question such as how to change the radiator on my car or a good blueberry pie recipe. The second is I might enjoy a particular "personality" like Joe Rogan or Jimmy Dore. I don't want to subscribe to car/cooking topics. Nor do I want to subscribe to MMA, general politics, or general comedy. This new model doesn't work for me. I wonder if I will be converted eventually.
