The ability to send money to makers of a video. For example, say there was one video in particular you relied on and really liked... and it helped you fix something that saved you money, you can in turn send that person a dollar or two (if not more).

I have a YouTube channel where I make about $500 a month with ad revenue and affiliate commission but I would think some of my videos could pay me out that much each month from these types of donations. Several of my videos I constantly have people saying things like "thank you so much you save me $700" etc... I would think I get someone who occasionally would donate 10 or 20 bucks for my awesome insight.
