Web Echoes is the product of my reading on the web. I post links and comment on items of interest to me. Generally the topics will be related to environmentalism, environmental technologies, environmentally friendly transportation, bicycling, but it may cover anything else that strikes my fancy, such as the occasional quiz or really cool web game.
