Got passed the URL for this journal yesterday and I have been reading the articles for the last day. It contains some very well written articles on the use of Digital Earth's in various ways. The International Journal of Digital Earth is the journal of the International Society For Digital Earth (ISDE) and this is the first issue of the Journal.
Here are the topics covered in this issue:

Digital Earth Summit on Geoinformatics: Tools for Global Change Research
One thing I noticed with the few articles I have read so far, the do not consider Google Earth to be a very good medium for data, and they considered NASA WorldWind and ArcGIS Explorer to be Digital Globes that are more what the guidelines recommend.
Two articles of interest that I have read so far are "Evolution and implementation of the Digital Earth vision, technology and society" and "The use cases of digital earth", these two articles have useful information for anyone wanting to explain about digital globes and if/why they may be of use for a project.
