Wood-Lewis started Front Porch Forum in his own neighborhood, the Five Sisters section of Burlington's South End. It's apparently been highly successful there — check out this mention in Cottage Living Magazine — so he's now expanded it to include all the neighborhoods in Chittenden County.
It's an interesting concept, though I wonder how well it'll take off in places like, um, Winooski, where I live. I would love to use it to communicate with my neighbors, but I have no energy to promote it. Beyond, you know, writing an article in the paper and mentioning it on my blog.
