As widely reported, Google has announced the debut of Google Earth Outreach. This service offers a set of great tools for users who seek to publish immersive, exciting Google Earth and Maps content. Though Google Earth Outreach targets non-profits, there are great tools for everyone there. Be sure to check it out.
What I find most exciting is the set of tutorials, some of which contain video-based instruction. Though some of the tutorials cover advanced topics, they describe techniques that most anybody can figure out and use. A great example is the Building Better Balloons tutorial.
