We have added the Boston Blogs Network to our watchlist. From their About page:

The Boston Blogs Network is a collaborative effort of a group of Boston-area blogs to promote each other and to sell advertising to local businesses tired of seeing their ad dollars wasted on clicks from people hundreds or thousands of miles away

Boston Blogs currently consists of 30+ blogs. It also has a directory listing 1,000+ blogs across the Boston area.
