I've been learning about Drupal Module Development the past few weeks. I'm using the venerable "Definitive Guide to Drupal 7" and a few times in the module development chapters (18, 19, 20), author Ben Melançon mentions running Drupal "in an IDE" to see how Drupal creates its various internal arrays.
I added a tag cloud to this BLOG. It looks quite nice, and I was happy with the tags except when I saw that that they didn't accurately reflect my content.
When I first deployed this change, the biggest tag was for "drupal", but when you clicked on that tag, you saw only one story. And conversely, the "c++" tag is smaller than the "drupal" tag, but there are three "c++" stories. Why was the "drupal" tag so large? And why was the "c++" tag so small?
