Chris Coyier [~31:57] on the present state of syndication: "We are in a rough spot".
That pretty much sums it up. We've spent the last 10 years happily enjoying the convenience of Twitter, and we've left many of the open alternatives wither by the wayside. Many of us are realising now that it's actually harder to syndicate content into several networks than it used to be back in the era of ubiquitous APIs.
I have things I post flowing in some way through Twitter, Mastodon and LinkedIn, but it's not ideal because I don't currently have a way to have full posts in my RSS feeds. I can't figure out how to add code syntax highlighting into the feeds, so at the minute I only include the description and a link to avoid a broken reading experience.
I like the new fancy federated protocols but I'd feel better if I had a robust setup for RSS reading, newsgroups/IRC and forums. #
