Childminders caring for young children in their homes have no apparent reason to use the Internet in their work. Yet a survey conducted by means of interviews and systematic analysis of traces left online has shown sustained work-related uses of the Internet by childminders. This article explores those uses. Blogs, forums, Facebook accounts with various degrees of public visibility, and e-mails structure this professional group in a flexible way, opening up spaces that animate the daily life of the profession: exchanges of experience and expertise, solidarity between “isolated” colleagues, and self-learning. Educational standards that are supposed to be more “professionalized” are disseminated online, leading to the exclusion, either directly (through lack of access to accreditation) or indirectly (through market sanctions and the absence of clients), of childminders who do not adhere to them, at least not formally.
