At first post Dreamr team mentioned comparison between other social media apps/sites and Dreamr. In that comparison section, Dreamr will also have secure communication services like WhatsApp. So users will be able to chat with each other?
For me what trumps whatsapp and make Dreamr a worthy competition is the help and dream achievement they are keen on providing. Outside this I don't see how Dreamr would be able to beat big social media outlets like whatsapp.
I don't think dreamr intends to beat the big social media like WhatsApp or Facebook. I believe that the focus is on creating similar features on the dreamr platform which gives the users a better chance of enjoying similar features on the dreamr app. It's agreeable that WhatsApp feature would be of immense importance in the dreamr app to help users chat and transact effectively.
