I have to thank Andrew Sterne for sending me this link to a excellent comparison info graphic. I think you will be able to better make a decision now regarding WordPress over Drupal. I was really shocked at how large the WordPress community is and how many sites are using the platform.
The data is indicating that WordPress is the most used and most user friendly CMS platform.
Great infographic. Really great way to look at the options and the cost associated with each option. These are things that we have known and never had an easy way to explain it to users but now have a simple graph to show them that will help clients make a decision on what to use.
