(Quite) a long time ago I was part of a team that was working on a product that was to change the world (yeah, every project you take seriously is one of those world-changers). The aim was not smaller than to give power to the user, power to the developer by letting them considerably more easier create business apps. Right now I'm happy to state – in a way the dream has come true. Siena and Light Switch are incarnations of the work I done literally a decade ago. What was changed? And how? And what is the difference? The aim of this series I start now is to look into the path that lead to these tools.
