Additionally the aspect of consuming YouTube via RSS feed. Feed readers could simply add small logic which transforms a given YouTube account into one of
https://www.youtube.com/feeds/videos.xml?channel_id=<account_id>
https://www.youtube.com/feeds/videos.xml?user=<account_name>
And so on for similar services. RSS has such great potential but somehow nobody uses all of it.Is there anything I miss? Why don't feed readers support external services (like the YouTube example from above)? Why don't feed readers add social features?
