There are 4 possible things I could do when I go onto youtube:
~ I go to My Subscriptions. I then click on the first video I see that I really want to see (if it's made by someone I love like ukinojoe, timmyfelldownthewell, cyriak, tpr, etc.). I usually then go on a long video watching spree sprouting from that video. To do this, I click on one of the related videos of that video, watch it, then click on a related video of that, and so-on and so-forth.
~ I have something i want to search in mind, so I go to the search bar and search it. This also sprouts a video spree.
~ I go to one of my subscription's channels and watch their old videos.
~ I go back to my favorites list and watch them again.
