I know some people in the web community are concerned that Baseline will discourage devs from using new features—or anything not "Widely Available".

Personally, I'm not worried about that at all. If anything, I think Baseline will speed up new feature adoption!

Here's why 🧵

I love this!

The country thats still defending is winning, the country that is breaking out tanks from WW2 in storage and attacking on donkeys and lost 900,000 men and got kicked out of Kyiv and begs NK for troops and Iran for weapons, isn’t.

Zelensky is a wartime leader watching his people suffer and die under Russian attacks every day. To be lectured and lied to by Trump and Vance, as they defend the war criminal dictator committing these atrocities, is unimaginable agony. An everlasting shame for America.

A hero and a coward are meeting in the Oval Office today.

And when the meeting is over, the hero will return home to Ukraine.

GLENN: Why don't you wear a suit? You're at the highest level in this country's office & you refuse to wear a suit. A lot of Americans have problems with you not respecting the office.

ZELENSKYY: I will wear a costume after this war will finish. Maybe something like yours. Maybe something better.

Trump and his administration are traitors to the USA, a danger to the USA and the world, and the most disgusting persons ever in the White House.
They are in Putins pocket.

Trump & Vance are monsters. Just absolutely shocking to bring one of the leaders of the free world into the Oval Office and dress him down to demand he thank Trump for Trump's greatness, while this actual leader tries to protect capitalistic democracy from Trump's flailing autocratic petrostate boss

Using ChatGPT's Memory to contextualize thought leader advic Using ChatGPT's memory, I contextualize complex marketing content, making it easier to understand and apply insights from industry thought leaders in a way I understand.

Take smart blog post URLs from thought leaders like @simoahava.bsky.social - put them in ChatGPT and let memory go back through everything you've talked to ChatGPT about and get ideas on how to apply it, in your context, instantly.

📣 Server-side GTM and Container Registry deprecation 📣

If you've received email about Container Registry deprecation, and you're wondering if you need to do something about your SGTM deployment – don't worry. Google has migrated the Docker image to Artifact Registry – you don't need to do anything.
