If you subscribe to a lot of YouTube channels like I do, YouTube’s native subscription system can start to get a bit clumsy, unorganized, and becomes easy to miss videos from channels in all the noise. So I subscribe to several channels using Feedly, which tracks new videos posted to the channels through RSS. It makes it much simpler to keep up with every single video being posted to my favorite channels even if I don’t go through my subscriptions on YouTube very often.
