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.
Hey YouTubers, starting every video on AI with "THIS CHANGES EVERYTHING" every week is getting really old real fast
Especially because usually... It doesn't ...
Hey everyone, time for you to put in the comments of the post below on why @thegoodlobby.wsocial.eu (or anyone really...) should not register on /move their accounts to W Social (and rather pick a better alternative like @eurosky.social, or even just self-host if they want to be independent)

Asked Claude to write my apology text and it suggested 'I acknowledge your feelings and will strive to do better.' Looks like I'm sleeping on the couch tonight
@popfeed.social could a setting be created to exclude already watch materials on pages like /find and in the recommendations block on movie/tv series?
I love getting the recommendations, but don't need to see mostly things I've already marked as watched :)
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.
Guido has a rare ability to translate community insights into tangible business intelligence, and to bring the business closer to the community.
