The World Wide Web offers much the same as the real world: news, weather, bargains, pictures, software, shopping, etc. But one aspect of life has been almost left out so far: meeting other persons. Meeting people on the Web is limited to very few places. We describe a model that enables people to meet everywhere, on each online-document. It is based on the concept of a dynamic neighbourhood which makes other Web users visible as a user surfs the Web. The implementation of the neighbourhood service presented is called Cobrow.
