    @KentNavalesi @julian Pardon me for butting in here, but I concur with this. The three solid weeks I spent on my (incomplete) search for Lemmy communities to follow via Mastodon was such a pain in the ass I never even tried with Piefed.

    @mobilizon Lemmy implements FEP-1b12. My software also supports this FEP so I can try from here too but I've never seen Mobilizon's Group in the wild.

    It has been an absolute privilege to listen to, learn from, and meet with the amazing people building the social web in East Asia! Taiwan has been incredibly welcoming, and I'm grateful for all the new connections from Taiwan, South Korea, Japan, and further afield. Thankyou to everyone who helped organize the Fediverse track at #COSCUP2026 - these events are always so informative and undoubtedly important.

    Context We had low turnout on the meeting on 5th August 2026, as we really need input from other taskforce members on what our next 12 months will look like, we will be having an interim meeting. This will be added to the W3C calendar shortly. When August 19th, 11am EST / 5pm CEST Agenda: Introductions, if necessary Brief Funding Update (5mins) Scoping the next year: Proposals Interaction Controls — replies collection usage, per-object reply controls, interaction controls, and consent respecting quote posts Suggested Milestone Items Issue Triage — lets look to see any other "obvious" candidates for work items (e.g., suspended, or some of the initial report items NOTE: This isn't a meeting to discuss implementation details, instead it's planning, as I need to get back to NLNet with a grant MoU soon. I will be moved the meeting along if we get too in the weeds. Outcomes: Each item should have a minuted vote for inclusion/exclusion, voting is -1 to +1, with -0/+0 as negative but no objection/positive no objection. We support contributions to the Agenda, please comment if there is something that we need to address during the meeting. Administrivia: IP Protection Note Reminder: Anyone can participate in these calls. However, all substantive contributors to any Taskforce Work Items must be members of the Social Web CG with full IPR agreements signed. https://www.w3.org/community/socialcg/join To contribute to Work Items: ensure you have a W3 account: https://www.w3.org/accounts/request, and sign the W3C Community Contributor License Agreement (CLA): https://www.w3.org/community/about/agreements/cla/ Reminder of Code of Conduct Scribe volunteer(s)? If we can't find a scribe, I'll need to record the meeting and use AI/ML to prepare the meeting notes, or the meeting cannot proceed.

    My favourite slide from my FediCon talk about Loops was the very last one I added at 3am the night before my talk."Someone hears about a thing, they go to sign up, and the first screen asks them to choose a server. And they don't know what a server is. They don't know what any of these words mean, and they've now been asked to make an infrastructure decision before they've seen a single video. Most of them just leave"#Loops #FediCon

    PM's should be working now as well. I'll look into the instance stuff not updating. As for the CoC it's hosted on dbzer0, I can't help you with that but if you ask in their Matrix chat they may be able to diagnose why you're hitting the honeypot. As for quokk.au's stance on copyright, it's anti-copyright but I also do not want to be hosting or directly linking to pirated/illegal content (i.e. torrents) so as to not invite potential issues. Just so we're not spamming [email protected] with bug hunting, do you mind sending me a PM or joining the Matrix channel ?
