Always nice to see your code working, even if it is a trivial gimmick: the hourglass countdown to next week's FediForum now has most of the sand in the bottom glass. Live: fediforum.org

My (single) slide from the panel at the EU office in San Francisco yesterday. It must have resonated because the other panelists also kept referring to it in their remarks!
Graphic. Left column: "From: centralized, autocratically governed, global-scale social media platforms" showing a prototypical but unnamed commercial social media platform with lots of users. 1 platform for the world, 1 approach to T&S, 1 leader in charge, 1 economic model (ads.
Right column: "Towards: locally run and governed, connected communities on the Open Social Web.." showing a federation with nodes with some random Fediverse and ATmosphere logos, with local communities around each of them. Thousands, millions of communities, T&S / governance / economic models by and as appropriate for the community. List of some key enables, and some term definitions.
And if you read it this far, I'm glad I took the time :-)

This is, I think, the "melting pot" at its best. Somebody went out of their way to research and making voting as welcoming to immigrated citizens as they could. In the outrage that much of the US is committing all the time these days, this is heartening.

I am at loss for words. From the SpaceX S1 filing. Can anybody even remotely believe this?

I'm kinda flabbergasted that all of a sudden, a very prominent "Fediverse" item has shown up in a prime location in the #Threads UI. It leads to all the posts of accounts outside of Threads that I'm following from within Threads via ActivityPub.

One thing I love about elections in California is how many options there are to cast your ballot. I chose to vote in person more than a week ahead of voting day. A certain sign of how much a party or governments supports democracy is whether they make it easier or harder to vote.

So if it is true, as I posted yesterday, that it costs about $1-$2 per user per month to run a social network at scale ... ... and if we wanted a big part of humanity to be able to escape the walled gardens ... we need just a bit of money. And donations. And volunteer hours. Totalling a mere ...

What would it cost to run the #fediverse at scale? With billions instead of millions of users? What does it cost to run a social network anyway? According to the annual reports of two companies that should know, the comparable seems to be about $1-$2 per user per month. And .. 1/2

The world we have -- in social media, and more broadly in tech -- vs the world we want. Does this look about right?

7% of people already are getting their news from AI, and it's not even something the AI companies are pushing. Given this incredible quote from Elon, and the blend of AI and social media he and others are working on, how long until the "news" that arrives with people is entirely fictional? 1/3

Social media has become the most used source of news. Commercial social media that is -- the one that has an opaque algorithm between you and the news that optimizes for the business benefit of the platform, not you getting unbiased news. What could possibly go wrong? 1/2

How big is the open social web, the #fediverse, #bluesky etc compared to the big commercial platforms? It's a bit sobering. From my recent talk "From millions to billions -- a plausible narrative for how to grow the open social web."

My neck of the woods is trying to get 7000 people out into the streets at the same time Trump has his Soviet-style, dictator-style, imperialist-style birthday military parade on June 14. Sounds ambitious? Yes. Important? Yes. Consider finding / creating a similar event in your neck of the woods.

CNN: “Putin considers Russia expansion. If he’s serious, a territorial expansion into Ukrainian, Georgia and Moldova would rival the Louisiana Purchase.” Oops, I must have gotten the imperialist wrong here. @cnn.com, are you out of your mind?

Modern HTML. Really.
About a dozen nested DIV HTML elements with lots of incomprehensible CSS classes.
