I was gonna add more to the list but at this point it would simplier to screen shot the two pages of youtubers I am subscribed to and just add on people who I watch sometimes but haven't subscribed to.
No Ali. Lots of people don't. In fact I only subscribe to youtubers I watch on a daily basis. Its easier to know when they upload something rather than always checking their channel. For youtubers that stop uploading after a while I just unsubscribe.
