I read a feed, clicked a link, clicked another, and another, and lost my path, but here I am at FeedMap:
FeedMap = Blogs + Maps
Using FeedMap you can geo-code your blog, browse already geo-coded blogs and search for blogs. Once geo-coded, you can get your own BlogMap location using a simple url that allows you to network with your local bloggers and much more!
In theory, it generates a dynamic map with other geo-located bloggers nearby, plus creates an OPML file, brings you coffee, etc.
I monkeyed around enough to get my own…
The first trick to get a FeedMap, is letting it know where your blog is- the magic is not really magic. One way involves adding meta elements to your blog headers, or adding tags to your feed, or you can just blunt force your coordinates in. For those in the US, there are address lookup tools from GeoURL that seem efficient enough. I imagine there are other tools out there as well to get your lat and long:

I tried the GeoExplorer which told me to Right-Click to add my blog, but that of course failed on my Mac (ahem, look who is behind the map technology). So I went ahead and added my geo-tags form above to the header of my blog, and plugged in the URL into the FeedBap form.
Strike 2.
Then I was provided a form to directly enter the lattitute and longitude I got from above. Bingo, I got a feed map, provided some JavaScript I can put in my blog:
It is in that “sort of neat” category but not really sure if it deserves a place on the front page. For example, the link to the “Neighblogs” supposedly shows the 82 bloggers around my office (it does not indicate my own location). Their locations are indicated by red numbers, but there is no information presented by hovering the mouse or clicking the numbers. I guess it refers to the 10 blogs listed bvelow the may (which are not even numbered, there are orange arrow buttons).
Or maybe it is just something that only works in IE on a PC.
I give it only one dog biscuit.
