I'm unsubscribing from all my YouTube channels. I'd like to say that this is because of some sort of moral objection to Google's data mining all the things, but it's really because my children have taken over my YouTube, and I'm more likely to get a recommendation from Google for some weird kids game than I am for something I'm actually interested in. Thankfully, YouTube videos still support RSS, so I'll just put the channels I'm interested in into my RSS reader and forget about subscribing.
