when people describe what they want for social media what i usually end up hearing is
[contacts list that uses something that looks like carrrd]
x [webhost + RSS]
x [account blocking]
- you can do 'retweets' via RSS,
- you can do 'only see who i follow'
- you can do 'only publish to some people' (subscriber-only feeds, though they are hacks)
- you can share arbitrary length things and arbitrary filetypes through rss
- the posts are yours because they live on your blog or whatever
you just need a contacts list that lets the magic happen. I don't have the cycles to go deep on it.
a lot of people derisively say "you are describing RSS"
instead I'm pointing at inspiration
@NireBryce you can do them with Atom. RSS doesn't have the source: element to say where it's reposted from https://www.ietf.org/rfc/rfc4287.html#section-4.2.11
