To be honest, I do not think Salesforce Marketing Cloud folk are ever bored given the challenges (and fun) the platform presents us with. But Custom Activities are really an interesting area to explore. With these, you can extend the default Journey Builder functionality and integrate with external systems. If you have custom activities you want to showcase, please come forward! We will host a demo jam, packed with custom activities that will inspire you to start developing some activities of your own!
