Is there any real or serious conversation or work around the idea of a feature-full social media browser?
Basically something like a web browser but for “all the social media” along with useful organisation features too.
For locked down big social APIs, this makes less sense nowadays, but for open alt-social systems, it is likely the most valuable promise of such systems that they can become like the web, reachable through an awesome all-in-one app.
I don't particularly understand the value of RSS readers at all
Notifications are the value for me. I don't have to regularly check infrequently-updated sites if my RSS reader pings me whenever there's a new post. Largely a different use-case to social media though.
