Into the feed of Currents, an open Pinterest alternative built on AT Protocol - Matteo Marjanovic
In this article I describe how I built the first version of Currents' feed, an open Pinterest alternative on AT Protocol, and how its personalization slider works.
On atmospheric generatives… - Scraps!
How can we build moats on an open network? How can we make money when all the data's free? Here, I sketch some ideas for new generatives — contextualization, fluidity, aggregation, and relationality — for value creation in the atmosphere.
Recommender systems and their ethical challenges
This article presents the first, systematic analysis of the ethical challenges posed by recommender systems through a literature review. The article identifies six areas of concern, and maps them onto a proposed taxonomy of different kinds of ethical impact. The analysis uncovers a gap in the literature: currently user-centred approaches do not consider the interests of a variety of other stakeholders—as opposed to just the receivers of a recommendation—in assessing the ethical impacts of a recommender system.

A Literature Review of Ethical Considerations in Recommender Systems for User-Generated Content in Human-Computer Interaction
The design of user-generated content (UGC) platforms poses challenges in comprehensively addressing the ethical dimensions of recommendation algorithms and applying human-centered methods for their evaluation. This article presents a literature review of 97 studies on UGC algorithms (UGCAlgos) that incorporate human factors and user experience considerations to investigate the ethical issues explored in human-computer interaction (HCI) research. Our review identifies key themes in the ethical considerations surrounding UGCAlgos and the user modeling methods employed. We examine how common ethical concerns in recommender systems, such as content appropriateness, privacy, user engagement, transparency, fairness, and diversity, are studied and contextualized within UGC platforms. Furthermore, we summarize how these concerns are addressed through user modeling approaches, including data characterization, user context, user outsmarting, interface design, user beliefs, and community and societal impacts.
