Now more than a year later from this article being posted. Digital nomad stage 3.0 is growing more than ever! Google trends show the search data for the word “digital nomad” to be continuing on a massive upturn. Niches like communities for digital nomads are getting more saturated with NomadList (like you mention in article), Reddit Digital Nomads and newcomer Digital Nomads Forum http://digitalnomadsforum.com/ — The advantage being that with so much competition, better and better platforms are being created for digital nomads. Even these three community platforms for digital nomads all offer different things despite serving the same community.
What will 4.0 bring? :)
