I seem to have missed the "abandon all RSS" movement, which doesn't surprise me. I am missing That One Puzzle Piece which enables me to understand why people ditched RSS in the first place. I'd appreciate enlightenment.
The (perceived?) reality is that social grows your user base and RSS doesn't. Publishers care about growth more than serving existing customers.
Another fair point... in general RSS can be thought of as "broadcasting to users" instead of the illicit "user engagement".
On another fair point though, the RSS app I currently use [Podcast Addict] has a "share" option with beget-plenty list of options [from eMail to Twitter]. I can't imagine other RSS apps not having the same in Current Year.
