If you scroll this page down a bit, you will see a rather cool “Blog Map” on the right side. This map is generated at feedmap.net, using the Microsoft MapPoint web service. I met with Chandu Thota, author of this cool tool, late last week. We are going to do some integration between feedmap and Syndic8 in the very near future.
If your feed is in Syndic8 and you have not yet marked it up with location metadata, now is the time to do so. There’s full information on the metadata help page.
