The way to "do drupal properly", which makes it so popular, is to use it almost as a "lego" platform, which is also much the same as how you would use wordpress. Both of them have such powerful plugin/extension frameworks, that most of the effort in building drupal or wordpress sites is finding the right plugins, and skinning. Very little actual programming work is required to get an operation site running for a client in either framework, which makes them ideal for many of these low-yield "corner store" sites.
