Please, please, pretty please, include a brief summary of your YouTube posts at the top of the text. I'm usually on my mobile device and don't want to click through to YouTube or to start watching the video to find out what it covers in more detail than the brief title. Plus there are dozens of videos on Steemit every hour and I don't have the time to check them all out.
I think by adding summaries you will get more click throughs, more views and more upvotes.
