Google Reader is the tool you use to read blogs.
After you figure out how to use the tool, you need to figure out what blogs to read.
Start with the class blog http://pprprofmv.wordpress.com and maybe with my other blog, http://www.prconnections.net.
As you discover other blogs or I tell you about them, you may decide to subscribe to them and read them. For example, Kevin Dugan’s The Bad Pitch Blog is a must-read. See my previous post about Kevin.
