What's going on just up Mass. Ave. in Cambridge? Find out at Cambridge Day, a site of news and opinion managed by Marc Levy. Advocate readers may recall Levy, a reporter for the weekly in 1994-95.

YourArlington.com is an experiment in community journalism dedicated to reporting news about Arlington, Mass., and the Arlington-related views of its residents. The experiment not unique but is part of a nationwide movement called "citizen journalism." The phrase gained currency through We the Media, a 2004 book by Dan Gillmor. This kind of journalism encourages members of a community to write about that community. The writing may be reporting, or it may be opinion.
