Had to think on this one for awhile, cause to tell you the truth, wasn't sure on how or what to vote on. So not going to place a vote, but just make this post. I think you should always mix the vid's up. If you keep posting the same vid's, it will get boring to watch them. Mixing them up will make it different, interesting, and people will be more interested. Maybe even making a type of game out of it with the "how to" tutorials. After watching one, see if you can have some sort of questionnaire to see what one may have retained after watching the vid by adding it to the end of the vid. Not sure if YouTube will allow you to edit a vid to post it with questions, making it like an Edpuzzle, or you could show a group of vid's, and after the short vid's have it where they click on the vid with the right situation. YouTube had this in beta in 2012, but not sure if it ever took off:

Whatever, or however you decide to proceed with this Ozzie, doesn't really matter to me. What matter's is your sincerity to continue in keeping the faith and backing to be a lifer to the cause!
