Currently we talk a lot about artificial intelligence. Yet, the more creative and human centered paradigm of collective intelligence has yet to generate the buzz that it deserves. There are many new technologies and platforms geared towards communication and collective interactions, and I will discuss why most of them, as currently implemented, lead us towards collective madness rather than collective intelligence. I will then point out some design principles that can help us to build platforms for collective problem solving and that could help us to realise the potential for collective intelligence.
