@Jeff, WP has a "monopoly" because it's fed by a huge community of devs and was settled by a default with a lot of hosting and a lot of strategies. I know about that because WP is one of the oldest CMSs from WWW. But if you take Google Trends and analyze other CMSs and then explore what makes WP successful, the answer is the same: an infinite loop between devs, hostings, huge documentation and passionate WP teams / community core which other CMSs just can't compete with. Here's one simple example: take one unpopular CMS and WP, and offer it to a hosting provider by default, which one would the hosting owner choose?
