🚀 NEW:

Podcasting is one of the most popular ways publishers share their work — and now you can run members-only podcasts on Ghost, with our brand new @TransistorFM integration

Quality writing 🤝 Quality audio

[Dr. Leif Singer @lsinger]

@Ghost @TransistorFM So cool! Which podcast would y’all like to see on Ghost?

[John O'Nolan @JohnONolan]

Today @Ghost crossed $10M ARR, as a bootstrapped non-profit foundation building open source software.

Indie publisher revenue earned with Ghost now ~$130M, and accelerating.

The world of technology is shifting rapidly, and so is the world of media, creators and journalism. It's hard to keep up with, and even harder to predict.

My strong belief, though, is that open software that you own and control is going to be even more important and relevant in the future than it is now.

So we're going to keep building it.

Google search is broken.

Social algorithms suppress links.

Finding good independent writing online has never been harder.

We built something to fix that: 🌍

November's Paper Jam was about using psychological research to influence the behavior of LLMs — super fascinating topic that makes me want to do some more research in my spare time.

@fahdananta @rashi_kakkar A grown man inciting racist hate is the polar opposite of playfulness.

🏚️ Broke:
Allowing spam subscribers to sign up to your newsletter, then bragging about iNcReDibLe gRoWtH 📈

💡 Woke:
Blocking those pesky little turds.

🪷 Bespoke:
Using Ghost's handy new spam filter settings!

[Birnbacherin @Birnbacherin]

Urteil für einen verbeamteten Feuerwehrmann zu diskutieren geht es ausschließlich um die Staatsangehörigkeit der Täter.

Nicht einmal die täglichen Femizide in Deutschland werden thematisiert!

Klar wird: Um die Opfer geht es nie. Merz nicht und der AfD nicht.

This wildly misleading tweet, and the mostly hateful replies, is like entering an alternate version of reality.

If anybody is interested in the truth behind this claim, and what that Swedish poll actually asked, I'll go through it.

Probably banging my head against a wall. 😂
