Greg Sterling has a great post today on his blog, Screenwerk. He is once again stressing the importance of local/neighborhood level search and advertising when it comes to differentiating between similar cities, towns, or general geographical areas that the larger search portals often get mixed up.
We all know the major metros get the coverage they deserve, but what about the little guy? For that matter, the “little guy” might just be in an outlying suburb of one of the metros and inherently get the short end of the stick due to the traditional “top down” national view of the portal approach.
Yet again, I’ll make my plea for the “bottom up” approach to this entire paradigm. eNeighbors aims to build a network of users that are tied together by where they live, not what internet portal they use.

well that’s exactly what we do. bottom up approach is how the 15k+ neighborhoods in the US are defined in our database. they can have multiple names, overlap, strange shapes, etc…
