I know it looks like it has a McLuhan theme, and it could, but initially I was thinking it would simply be a way for us to communicate with each other easily, i.e. Gerry's Dudley films, events Michael's going to, Robin observations on the road etc. You can post pictures. Videos as well, but I'll have to sort out those details as things evolve. If they evolve. At the very least I'm going to use it to post links to McLuhanesque newspaper articles, etc.
