I find stuff I like via the algorithm very often. Subscriptions cover channels that I want to see every upload of, but that doesn't cover channels I don't yet know about or channels only have a percentage of videos interesting to me. I use the algorithm mainly for finding content that I wouldn't have discovered otherwise, and I can tell the algorithm knows to suggest me videos like that (low view/sub count videos show up for me way more than normal).
Great client but unfortunately for those of us on private trackers it isn't going to be whitelisted on many of them, or at least the most prominent ones. At least that was the case last I checked, and I gave up on it after.
Yeah I can't wait to use these glasses to replace my glasses.
