10 years ago today the first #federated#IndieWeb comment thread was published and collected peer-to-peer IndieWeb replies across websites without any intermediary, silo or otherwise¹.
2013-04-19 @eschnou.com posted a brief note on his personal site with #atMentions of a few domains (putting an '@' sign immediately before a domain name to indicate an explicit cross-web @-mention), which itself was also a first²
When @aaronpk.com was notified and replied from his site within minutes³, it became the first peer-to-peer federated IndieWeb comment thread, at the time using h-entry and Pingback. I blogged about it a few days later⁴.
Unfortunately Laurent Eschnou’s original post is no longer up, and we only have the Internet Archive copy. However most of the IndieWeb reply posts are still up including Barnaby’s: https://waterpigs.co.uk/notes/1334/
The oldest still working federated post and comment thread was second overall, unsurprisingly from @aaronparecki.com⁵, a whole 40 days after Laurent’s first.
