There should be a little 5 minute "class" at sign-up on how to bring good content to steemit. I see a lot of people writing two sentences with a YouTube video link, and the sentences are "I made this video. Check it out!" The video may be a good one, but lets assume that not everyone can watch a video right then and there. Having a thorough synopsis with acouple photos from the video would get the upvotes, and those who wanted could watch the video later.
