Learn from some of these incredible city innovators as we head into the next decade and beyond.

The 2010s brought on the adoption of social media as not just part of but in many cases the driving force behind main stream public discourse. In an increasingly polarized nation with politics becoming a bloodsport, Twitter, for better or worse (typically worse…), is the venue for where many of those matches are fought. While the downsides of Twitter are well known and well publicized, the question always arises, how do you cut through the noise of social media to gain the valuable insight dispersed between political arguments.

Twitter, after all, does still have an extremely valuable place in the today’s society, particularly in todays growing new urbanist conversations. With an ever evolving world and a growing desire to live in walkable urban centers, it’s more important than ever to learn and share best practices with folks from around the globe and join a “global advocacy network” to fight for our shared ideals. Ideals that we know will make our cities and towns more vibrant, connected, healthy, affordable and equitable places to live, work and play.

The list below consists of just a sampling of some of the folks creating that future in our global cities and towns. They are experts in their respective fields, active advocates on Twitter sharing their insights and examples of their work. They wake every day with a “mission” to improve the way each and every person lives, works, and plays in and moves about their city and a drive to achieve it.
