I don’t like putting business videos on YouTube. Especially the videos that I need to embed in my website. That’s because of the non-controllable video suggestions at the end of the video playback. It may distract and redirect the reader from my site to the next funny videos.
The same applies to Medium. In Medium, my readers may get taken away by the suggested posts which are controlled by Medium’s system. So I don’t feel comfortable to put my essays on Medium.
Of course, this does not apply when we treat the YouTube and Medium as a social platform. They are a good platform to gain new readers and get shared out.
