Google has (finally) announced a way to embed Google Maps in webpages, in much the same way a YouTube video can be embedded. We're going to see if we can create a [[*map=...] (like we have for videos and images now) so you can drop these in anywhere in your blog posts.
We'll still be keeping our Map structured data extensions, as that actually has semantic meaning toward the post (plus we can do other tricks, like navigating between posts with a map!)
