Thanks for sharing! Having read your blog post, I'm intrigued...but I'm not understanding the process involved in "curating" items between the tiers. It could be that i'm overthinking what you described, but I'm certainly curious to learn more about your process. I look forward to reading any follow-ups to this piece. :-)
Curation is the process of selecting items from a data stream. When you browse youtube, clicking on one link over another is a form of curation. You may watch the video for 1 min or the whole thing. Or you may watch for 10s and save it for later. That is another form of curation.
Then suppose you download the video via youtube-dl and store it in a folder. That is also an act of curation. And finally, if you watch the video every day, post it on a blog, use portions of it and edit it, that is also a form of curation.
