If you thought causes were no memes, then have a look at how Studio Brussels (Flanders coolest Pop and Rock radio station) unlocks its potential towards youngsters to advertise its party night:
Dear very consious younger generation, we know you are aware of what's going wrong in the world, are opinionated, but feel so unable to really do something about it. Don't feel guilty for just once. Let all 'Weltsmertz' go.
'Have a great night, you can save the world another day'
On top of being a great idea, it's also a smart 'generation insight'.
