How does an institution encourage curious minds to connect? How and why does it generate or foster the building of a community? What do the various parties gain from it? Two cases will be rapidly presented about two different types of communities connecting to an institution: teenagers and a diverse mix of visitors. The speakers will focus on why their institution decided to connect to such communities, how they went about building them or fostering their growth, how they stay connected and “work” with them, how the communities evolve, what they gain… The challenges and opportunities of building various communities or connecting with them (they could also be artists, entrepreneurs or other professionals) will be discussed with participants with ample time for debate.
