Fred Wilson has an interesting post on some of the hyper-local websites that are out there. I really like the design of BackFence. I think that's got a lot of potential in huge communities like DC, where, for example, the Washingtonpost.com site may just be too massive. And/or it may not lend itself to discussion. Toll road rates going up? Giant Giant food stores? Lots of interest there from the folks in the community.
