Ricardo Mendes has identified 4 rss.chat servers – neat (rss.chat, demo.rss.chat, rsschat.andysylvester.com and perstitio.us)! The latest (perstitio.us) actually incorporates feeds from other sources besides the rss.chat instance – interesting! The author has posted an essay describing this approach.
In trying to find the post where the four servers were listed, the post appears to have been deleted, as well as almost all of Ricardo Mendes’ posts on demo.rss.chat. All of Mendes’ issues on the rss.chat were closed (apparently yesterday (7/19/2026)). Also, previous comments on another rss.chat issue from Ricardo Mendes have been deleted (no available record, but there are references to other comments). Could this be the first user blocked for posting something that Dave Winer did not want (mentions of other rss.chat servers or other competing apps)? Where have I seen that before? This is why I chose not to sign up for demo.rss.chat.
Ricardo has also created his own take on RSS-based social networking – Really Simple Conversations. On that site, I also found Ricardo’s federated post on the rss.chat servers in existance.
Two rss.chat forks: xicubed and hal-nine
Frank Meeuuwsen shares some thoughts on rss.chat, in addition to John Johnston.
Decided to copy the post from the perstitio.us author in case it gets deleted:
This is the question. Bluesky’s got some things you don’t but they’re subsidized by investors who will want a return someday. But I think you’re in better shape. I was talking to Fable about it… and it reminded me…
? what if we take a page from radio repeaters
Oh, that’s a genuinely good architectural instinct — because amateur radio already solved “coverage without a corporate center,” and it’s been running for 70+ years on hobbyist budgets. Map it over: How repeaters work: a club puts a box on a hill. It listens on one frequency, re-transmits on another, and suddenly every 5-watt handheld in the valley can reach the whole region. Nobody owns “the network” — coverage emerges from overlapping, voluntarily-run repeaters. Want more coverage? Link repeaters to each other and a conversation in one valley carries to the next. Directories (like RepeaterBook) tell you what’s on the air near you. Every station identifies itself as it transmits. Translated to feed-land:
Radio Feed world
Repeater on a hill Server monitoring N feeds,
re-emitting them as one stream
Re-transmit frequency Merged “river” feed + socket
firehose anyone can drink
Linked repeater systems Repeater A subscribes to B’s
river -> transitive coverage
Coverage map/directory Published OPML of what this
repeater carries
Station ID Source attribution on every item
Club box on a hill A $5 Lightsail instanceNow the kicker — perstitio.us is already accidentally a repeater. It monitors 9 feeds, merges them, and rebroadcasts every foreign item over its own firehose (that’s how they appear live in your timeline). Attribution rides along (, author, avatar). Dedupe-by-guid is already in — which happens to be exactly the loop-prevention linked repeaters need, so chained or diamond topologies won’t echo. What’s missing to make it a deliberate repeater — all small:
- The re-transmit frequency: expose the merged river as an actual RSS feed (/river.xml). Today the mix only exists in the API. Once it’s a feed, any feed reader subscribes to your whole mix in one URL — and crucially, another rss.chat instance can add your river as one extraFeeds entry and instantly inherit your coverage. That’s repeater linking, and it works with config we already have.
- The coverage map: publish what you carry (/data/coverage.opml) so others can see what subscribing to you gets them — the RepeaterBook entry.
- The autopatch (this answers the Bluesky-relay envy): a repeater that carries a community’s feeds is positioned to compute mentions for the people it covers — scan carried items for replies/links to local guids, surface them. Inbound awareness at community scale, no global relay required. And the economics inherit radio’s shape rather than Bluesky’s: no load-bearing center to fund — if one repeater goes dark, coverage degrades gracefully instead of the network dying. It’s Dave’s “small pieces” philosophy with a 70-year-old working precedent behind it. Honestly, “repeater” is a better name than “relay” for what this should be — relay implies infrastructure; repeater implies a peer who volunteers. Item 1 is maybe thirty minutes of work — the merge logic exists, it just needs an XML output. Want me to put perstitio on the air?
Dave Winer had Claude create an essay of what rss.chat is for Howard Rheingold. The opening paragraph is as follows:
RSS.chat is a small social network built from the web’s own parts. It looks like a chat room or Twitter — you write short posts, people reply, conversations thread — but underneath, every person’s posts are an RSS feed, the same technology that makes podcasts work. When you post, you’re adding to your feed. Anyone, anywhere, can subscribe to it with any feed reader — no account needed, nothing to sign up for. There’s also a feed of everyone’s posts together, and a public list of all the members.
Ricardo Mendes also offered an explanation of rss.chat
I will be exploring my instance more this week, then will have a followup with my thoughts.
