This is exactly what I don't understand about all the feed readers out there.
It seems so obvious that the next step for feed readers would be social interactions like sharing, also it would be to easy to add I guess.
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?
