My neighborhood association has started a blog to help disseminate information more quickly and easily than can be done by means of the printed newsletter (though we're not giving up the newsletter).
I like this post about the congruence between historic preservation and "green" building. Key quote:
Rehabilitating existing buildings is almost always more environmentally efficient than tearing down and building anew. Maintaining and improving historic buildings and the neighborhoods in which they stand allows for the continued use of valuable infrastructure.Paula Patch is running the blog on behalf of the neighborhood association.
