If you live in Massachusetts and want to keep up with the latest news from Beacon Hill, then add a bookmark for MassInsider, a site devoted to tracking the latest news and opinion concerning policy, lawmaking and politics in the Bay State. The site is still in beta and has not been formally opened to the public yet, but it is already well along. Its main feature is tracking news articles and editorials from newspapers and wire services. It will also have links to media sites, political blogs, think tanks advocacy and labor groups, political organizations and state governments. The site is being launched by Michael Segal, a former journalist and author of the book, Dukakis: The Man Who Would Be President. Segal also operates InstaTrac, a Massachusetts bill-tracking service.
