Great motivational speech @Kees_van_Gelder 
I’d like to add that everyone is invited to write tutorials and post examples. Over the last couple of months we have acted on the importance of the Tutorials & Examples forum category. The category moved from a buried subcategory to it’s own main category and now has its own subcategories for everyone to contribute and discover ideas.
Home Automation as is is a complex diverse field. openHAB tries to cope with this complexity by providing numerous possibilities. The learning curve is steep as you said, Tutorials and Examples will help everyone to make the most out of it.
Happy Hacking everyone!!
