Look at the list of "liked videos" on my channel.
This is a history of what I recommend.
Look at the interesting screen shots that come from videos in some of these channels.
This is a way of explaining WHY I subscribe to these channels.
The screenshots show that I took time to look at some of these videos and I can type something to explain WHY I recommend these videos.
You can display these recommendations on a document in Google Drive or in a blog post.
I have a blog called Interesting Things where I can show some of these items.
