The Silicon Valley Computer Genealogy Group has a web page that I periodically go to for information. When you reach the home page, click on "How To's and Helps" to be taken to a menu of hints, tips, articles, and classes.
Many of the offerings deal with PAF (Personal Ancestral File), but there are several that deal with general genealogy topics as well.
In the "How To's and Helps" page you can view a document that briefly explains how to use the "New Famly Search." That is not available to everyone just yet, but the article gives a good idea of what the net-centric replacement for PAF is all about.
