How to understand the role of NEM core dev. team? NEM core dev. team should be considered only one group (albeit, an important one) within the NEM overall community- but not a centralized representative of NEM community. That means I would encourage NEM stakeholders to self-organize different teams/ groups that can operate independently from NEM core dev. team in a truly decentralized fashion, especially regarding to marketing and promotional activities. This I believe will increase the resilience, the diversity and the creativity of the network as a whole.
This should be considered a Prologue to NEM operation after the official launch, not that I ask the community for these decentralized activities right now - It is expected that we will fill the large bulk of all NEM necessary works (marketting included) up until our official launch, and probably extending until V1 blockchain completion as well.
