This post is a no-brainer. John J. Gardiner, a technical writer at Google and the author of the Google Earth user guide, has just launched a new blog (as one does): Using Google Earth. John writes:

The idea is to describe features of Google Earth that might otherwise be unknown to many users. Initially, I will focus on serving less experienced users, but I will discuss more advanced topics soon. I will also post some original KML content for folks to explore. Let me know if there are topics you would like to see addressed on this new blog. Thanks!

Which reminds me: I really need to update my link list.
