From the urbanists' perspective, the everyday experience of young people, as an underrepresented group in the design of public spaces, includes tactics they use to challenge the strategies which rule over urban spaces. In this regard, youth led social movements are a set of collective tactics which groups of young people use to resist power structures. Social informational streams have revolutionized the way youth organize and mobilize for social movements throughout the world, especially in urban areas. However, just like public spaces, these algorithm based platforms have been developed with a great power imbalance between the developers and users which results in the creation of non inclusive social informational streams for young activists. Social activism grows agency and confidence in youth which is critical to their development. This paper employs a youth centric lens, which is used in designing public spaces, for designing algorithmic spaces that can improve bottom up youth led movements. By reviewing the structure of these spaces and how young people interact with these structures in the different cultural contexts of Iran and the US, we propose a humanistic approach to designing social informational streams which can enhance youth activism.
