Using Drupal

When you look at CMS (content management software) usage statistics, such as here
you realize how dominant WordPress is in the marketplace.  That’s due to cost, ease of learning, growth of the software, and frankly, a job tremendously done by those who develop software in the WordPress marketplace.
But the point of this short post is about Drupal. If you look at the entire web on the stats listed above, you see that it’s behind WordPress and Joomla! in terms of entire sites.  However, when you look at the most popular sites on the web, whether it is the top 10,000 or the top million sites, Drupal is second.  In fact, Drupal’s marketshare in terms of powering sites increases when you look at the more popular web sites.
Why is that? 
There are less web developers out there working in Drupal than what you see with WordPress – much less.  The developers that work with Drupal point to the scalability, security and sturdiness of Drupal for development, and when you think about high volume traffic sites, these are key qualities in looking for a content management system, particularly with Enterprise level web sites.
This site 
shows the migration from one CMS to another the past several years.  Drupal has been growing, nothing like the growth of WordPress but still growing.  One trend seems to be the move from Joomla! to Drupal.  But it is hard to get a complete handle on this in the marketplace at this point.
