As an interesting aside, I’ll note that just a few months ago that YouTube allowed people to do embeds with several options, but they’re recently removed the option to prevent their player from recommending additional videos once you’re done. Thus the embedding site is still co-opted to some extent by YouTube and their vexing algorithmic recommendations.
In a similar vein audio is also an issue, but at least an easier and much lower bandwidth one. I’ve been running some experiments lately on my own website by posting what I’m listening to on a regular basis as a “faux-cast” and embedding the original audio. I’ve also been doing it pointedly as a means of helping others discover good content, because in some sense I can say I love the most recent NPR podcast or click like on it somewhere, but I’m definitely sure that doesn’t have as much weight or value as my tacitly saying, “I’ve actually put my time and attention on the line and actually listened to this particular episode.” I think having and indicating skin-in-the-game can make a tremendous difference in these areas. In a similar vein, sites like Twitter don’t really have a good bookmarking feature, so readers don’t know if the sharing user actually read any of an article or if it was just the headline. Posting these things separately on my own site as either reads or bookmarks allows me to differentiate between the two specifically and semantically, both for others’ benefit as well as, and possibly most importantly, for my own (future self).
