For 21+ years I've helped tech teams turn developer & customer intelligence into product strategy, grounded in cognitive psychology and a habit of testing my assumptions. I help build communities, and the teams that run them.
I tried answering "How big is AT Protocol in Europe"
It's still an evolving story (and data collection script), but here is my first attempt: atproto.eu/stats/
It includes a breakdown per country, growth chart, PDSes used and the apps/lexicons are most used (beyond microblogging).
What if, for a year, we as atproto community focus on improving a major community lexicon every month
We improve the hell out of it (if needed) and then integrate into existing apps where it makes sense and help each other to do so
There's a new king 👑 in town, slackers @angrydutchman.online@chris.pardy.family@samclemente.me@murdabea2.margin.cafe@jauntywunderkind.bsky.social@natespilman.at@borisanthony.net@byjp.me@scanash.com@marque.at #SeptemberGives
Funny story: I had several people warning me that the apple developer program takes forever to get in.
Turns out I registered for this back in 2011 (only paid once, totally forgot about it). It was dormant ever since and I could just reactivate it without any hassle 😅
My ATproto sideproject escalation levels & full-circle moment:
L1: Let's build an AI-powered personal conversation starter github.com/gxjansen/Blu...
L2: Build a forum @barazo.forum
L3: Build a trust/reputation layer
L4: Build a way to manage your professional profile/reputation @sifa.id
Can we get the post below to at least 487 likes to make it the most liked post about ATmosphereConf?
Or should we save that for the actual date/location announcement? 😄
@atstore.fyi would it be possible to add an optional "builder location" field?
That way it can be used to create "locally built atproto apps", which is useful for local atproto community websites, e.g. atproto.nl/tools/
(And also building this for be, no and eu-wide)
I lean on two things that don't always sit together: a cognitive-psychology read on how developers and customers actually behave, and an experimentation
habit (those 500+ A/B tests at Randstad & JDE) to check what works instead of guessing. I'm
still learning, mostly in the open.
Cognitive psychology
Why developers and customers actually behave the way they do.
Business experimentation
500+ A/B tests at Randstad & JDE. Measure what matters, prove what works.
Community building
Helped grow the Joomla!, Magento, CRO.CAFE and Spryker communities.
(AI) automation
Reliable AI workflows and local-first tooling that earns its keep.
