This master thesis reports on potentially useful applications for “The social layer concept”, consisting of a combination of telephone-based health advice-giving and dynamic marking of shared web pages, with the aim to contribute to the online health counselling domain. An experimental user study was performed to test a web marking tool prototype. The experimental tool was shown to be useful in helping clients focus on relevant health information and dynamic web marking does provide a useful and complementary service to telephone-based advice-giving. It was considered most useful for complex health advice-giving issues.
