This article argues that the emergence and growth of internet use in Britain has important implications for the analysis of social policy. It attempts to outline a research agenda for social policy in relation to one particular aspect of internet use, that of on-line self-help and social support - what we term here virtual-community care . The article presents data on patterns of home based internet use in Britain and outlines some contemporary debates in social policy about the importance of self-help and social support. It also considers how the internet is being used for self-help and social support with a particular emphasis on the emerging situation in Britain. Three illustrations of on-line self-help and social support are presented: two from newsgroups, which are part of the 'uk.people.* hierarchy': one concerned with disability and one with parenting issues; and one web based forum concerned with issues surrounding mortgage repossession. Drawing upon this illustrative material the article discusses some emergent issues for contemporary social policy discourse: the rise of self-help groups; the privileging of lay knowledge and experience over the 'expert' knowledge of health and welfare professionals; the nature of professional-client relationships; the quality and legitimacy of advice, information and support; dis/empowerment; and social exclusion.
