I've been meaning to post about our new blogger maps at outside.in -- they were a little pet project of mine, and I'm pretty excited about how they turned out. As I've mentioned before, one of our guiding principles from the beginning has been that maps shouldn't be a prominent part of the interface, because people really don't read maps (unless they're looking for directions.) So the basic outside.in UI has the map as small as possible -- it's there to give you a basic sense of your location and zoom level and a mechanism for moving around through space -- and that's it.
But ever since we launched our place pages, which tag posts and stories with specific locations (schools, restaurants, etc), it's been clear to us that we can track the places that bloggers have been writing about in ways that most bloggers themselves can't easily do. So we thought it would be fun to create blogger maps, in a part as a service for the bloggers themselves, whose work we rely on in multiple ways.
But we didn't want to just put pins on a map for each place the blogger writes about, because for the blogger him or herself, that's not really news. When Brownstoner writes about the new Brooklyn Bridge Park pool, he doesn't need to see its location on a map -- he already knows where it is. And I'd wager most of his readers do as well.
Which gets to our other guiding map principle: the map has to show you something new.
So we decided to use the map as a discovery mechanism as well -- showing not just the territory covered by a specific blogger, but also the overlap with other bloggers who have written about the same places. So if you look at the Gowanus Lounge map, you can see recent places he's covered on the left, and then a series of orange and black "pies" on the map corresponding to each place. The size of the pie shows you how many total stories we have in our system about that place, and the ratio of orange to black shows you how much that conversation has been dominated by the current blogger. When you roll over each place, you can see headlines from all the other stories about that place.
We think this view adds a huge amount of information to the original blog itself. You can see in a single glance:
1. The general geographic focus of the current blog
2. The names of the places the blogger has written about lately
3. How active the conversation is about these particular places (ie, how many stories)
4. How crowded the conversation is (ie, how many other blogs are participating in that conversation)
5. The headlines from those other blog posts.
Now, if you knew the neighborhood well, you might be able to read through a blogger's posts and figure out #1 and #2 after a few minutes, but it'd be impossible to see #3-#5. It literally gives you a whole new view of the original content, and also manages to connect it to a wider conversation.
Cool, huh?
