Hm, I hate to be on the bandwagon, but why WordPress? One of the things that has made PHP become what it is today is a focus on good software engineering and the introduction of language features that are required by that. WordPress did not keep up on the engineering front and there are so many amazing options out there now for well written, well engineered platforms. Even in pre-built blog platforms.
You're not alone mind you, most of the new platforms are not very popular just because of how embedded WordPress is in its ecosystem. It just surprises me that both WordPress never moved on and that the PHP developer community never chose something different when it was clear WordPress had no intention of moving to more modern practices.
WordPress can't really become better without becoming incompatible with itself. It was written just after PHP acquired classes, but chose to preserve compatibility with a codebase that predated that. It's its own ecosystem at this point.
I am completely out of the loop here. All I know is that I really disliked Wordpress and really-really disliked Drupal back in the day. Can you mention some of the better alternatives? Once in a while a PHP CMS is what I gotta deal with and I dread it, because of the said systems.
Check out OctoberCMS. The simplicity and ease of use of PHP while being a very modern and stable platform to build one. Disclosure: I'm the community manager :)
Clients see Wordpress as a business platform/lack of dedicated supported in-house and developers on projects based could keep generate incomes from small businesses.
What are the amazing option do you suggests with batteries include in the language would be ideal.
