Yahoo! Neighbors has been expanded nationwide from its four trial markets: Bay Area, NY Metro, Dallas, Chicago.
Here’s my original post from November, 2007 when Neighbors first launched in an early trial form. Neighbors is a mix of Yahoo! Answers and Upcoming (to a lesser degree). The danger is that Neighbors becomes a repository for spam. And there will be a bit of a cat and mouse game to keep it from becoming that. Provide it doesn’t get taken over by spam this will be a valuable local resource.
Matt McGee at SEL does a nice job with a features overview. He also discusses the SEO potential of Neighbors.
This is clearly not the first integration of Q&A or “conversations” into local — most recently YPG in Canada launched an Answers product (using Praized) — but it is a relatively high-profile one. To work you’ve got to get lots of participation, which implies lots of scale. Yahoo! Local has fallen considerably from its perch as the best/most visited local site several years ago. But it remains a powerful and visible player in the local segment.
