Content - there's an app for that
But honestly, it would be good to see it as a motto for our conference, a claim which we'll use on displays announcing the next talks and so on. So it shouldn't be too simple and shallow.
For me it goes into the direction of promoting "meaningful content", leaving behind the "page / print paradigm", exploring the true domain of the respective projects (through DDD and content modelling).
Something which wraps it up but is a bit worn out is "content first".
A claim which would be more open tease a bit would be "What does it mean?" Maybe we can phrase it better. But something related to "meaning" would be nice.
