FWIW, I attended the tutorial he gave on the tool at AAG last month, and it's really quite an interesting tool.
I strongly suggest reading the appropriate ACS Compass guide(s).
I look forward to working with it more.

The project was funded by the U.S. Bureau of the Census. The data for small geographies, such as census tracts and block groups, were released earlier this year. Due to the smaller sample size for the ACS compared to the 2000 Census long form data the MOE for these ACS data are relatively larger. When presenting the ACS data for small geographies on maps the cartographer should advise the viewer of the reliability issues. David Wong’s extension provides assistance in doing this. It also has good instructions that explain how to download the ACS data and handles the joining of map and attribute data. The extension and background on using ACS data may be downloaded at: http://gesg.gmu.edu/census
