The Zeroth Loop: They Don't Quit, They Forget | Mike Bifulco
Most habits don't fall apart because people quit. They fall apart because they aren't sticky.

People attach to products in 3 steps:
marketing -> first use -> proven value
Rather helpfully, this maps well to the cue-response-reward pattern for building new habits. Definitely some useful psychology to understand.

Our team at Craftwork recently opened expanded to Raleigh, and I’ve been enjoying learning how the city’s neighborhoods tell very different stories.
Today I want to talk about Historic Oakwood.

So Craftwork just expanded to Raleigh - and I'm having a great time learning about the neighborhoods and history that shape the city.
One of those is Mordecai.

Agents, subagents... dev work is changing so quickly, it's a very interesting wave to surf.
Lots of our old skills are now commoditized. There will be an important shift from coding to communication for lots of engineers. That's a huge career change for many of us

Everyone has impostor syndrome, pt. 3107828: I was tagged in a post on LinkedIn as part of the "Stripe Mafia" (lol) -- because of Craftwork's fundraise from last year.
I do not feel like I belong on this list, for sure.
As a bonus - this has made my inbox on LinkedIn even less useful...

So: counting clicks isn't a good measure of a design. But what is?
The answer, unsurprisingly, is "it depends". But you should be able to pick goals and measurements that _are_ good indicators of how well your feature is working.

Beyond Click Counts: Finding the Right Signals for Good Design | Mike Bifulco
Click counts are noise. Real design success is measured in signals that show whether people actually achieved what they came to do.

"Too many clicks" isn’t your problem.
It's a signal that your design isn't getting the job done. Clarity, confidence, and cognitive load are the real culprits.

Slack changes its API rate limits, another sign that the web is becoming more closed off due to LLMs. Ktor is giving you even more reasons to use it, all that and more in this issue of the @apisyouwonthate.com newsletter.

About Slack's new rate limits...
As APIs become the sneaky backbone of LLM-driven workflows, Slack's update to their API rate limits may be an interesting sign of changing tides.

My first product launch failed - and it would have been _so easy_ to avoid.
In the end, smpl was acquired, but it could have had a dramatically different trajectory.

Hello, @clt-urbanists.bsky.social 😍
“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.”
Better for the climate, better for health, better for livability & quality of life.
Common sense.
Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.
