Windows Live Writer - Publish Maps
Microsoft have launched 'Windows Live Writer'
This includes Map Publishing
"Whether you are blogging about a vacation or a political conflict, maps are a great help in engaging the imagination of your readers. You can do this using Writer's ability to insert a Windows Live Local map directly into a post.
Even better is that the map can be customized directly within Writer - including changing the view to show road, aerial or bird's eye detail and by adding pushpins (including custom links and/or photos for each pushpin).
When readers click on the map they get a larger view on the Windows Live Local site."
