Ik had een leuke middag, met onverwachte inzichten.
Jacco maakte het eerste uur even tijd: hij is druk bezig met klussen in zijn vintage-winkel die binnenkort opent.
Het tweede uur sprak ik met Hans en Martijn over privacy, big tech en de vrijheid om je eigen pad te kiezen.

If I were launching a social media about truth and verification I'd, like, try not to lie but that's just me.
Anyway, some of us have work to do.
