The “Like” button is a feature commonly found on médias sociaux[1] platforms that allows users to express their appreciation or endorsement of a post, comment, or piece of content. Originating from platforms such as Facebook[2] et LinkedIn[4], the Like button has become a staple on numerous other social media platforms including Instagram[3], Snapchat[5], Twitter[6], Vimeo, FriendFeed, YouTube[7], Google[8]+, Reddit[9], VK, TikTok[10], XWiki, among others. The implementation and use of the Like button vary across these platforms, all with the shared goal of fostering user engagement and content visibility. Over time, the functionality of the Like button has evolved, with the introduction of reaction buttons, hiding like counts, and even the potential removal of the feature due to controversies surrounding its impact on mental health, vie privée[11], and spread of misinformation. The Like button, while simple in design, plays a significant role in shaping online interactions and user behavior.
