One of the things we've been wrestling with from the very beginning with outside.in is how to get contributions from blogs or media outlets that only occasionally write about local issues. We're already automatically indexing content from full-time placebloggers -- people who write consistently about their communities -- but it's a trickier issue for bloggers like me who write about their neighborhood (or other neighborhoods) once every ten posts or so. We want to be able to capture those posts, without having to capture the other nine posts that aren't relevant to a location. From the beginning, we've had tools that let people suggest specific stories to outside.in using our suggest story tool and bookmarklet, but today we've just rolled out a very cool alternative: a Feedburner "geotag this post" flare. You can see it working here on my blog already. If a post hasn't been geo-tagged yet, you'll see a little invitation to "geo-tag this post." Once the post has been tagged though, the flare identifies the zip code and gives you a preview of how many posts we have for that zip code at outside.in. And then you can click on the link and go straight to a neighborhood overview page for that zip. (See my Rushkoff post for an example.)
If you're already using Feedburner, it's trivial to add the outside.in flare to your blog. Fred Wilson has a good overview of how you add flare generally, as well as this post that explains why he's excited about the outside.in version.
