Well I think you are missing the point, no? This website is exactly that, DO. And I like the idea of forcing yourself to post a video every day, it kind of obliges you to actually DO as you say :)
No. You are missing the point. I can see people signing up to DO, say, Learning to Play Ocarina -- https://giveit100.com/@LylyB -- and then OBSESSING with making the Giveit100 Video for the day more than actually LEARNING to Play by DO-ing!
