Fair question. There are dozens, if not hundreds of content management systems out there. So I think the question to answer is when we decided to go away from ProofBuddy as a free standing web application, why did we settle on WordPress instead of one of the others.
The biggest reason we went with WordPress is user requests. Since ProofBuddy 0.7 was released the most common questions we get are how to get ProofBuddy either embedded into WordPress or looking just like a WordPress site. And by common, it’s a question that we get at least once a week so over the years that ProofBuddy has been out we’ve had hundreds of users wanting to use ProofBuddy and WordPress together.
In that same amount of time there’s been one user ask for Drupal integration.
So we went with numbers. WordPress is staggeringly popular. It powers something like 17% of all websites, including some of the really popular ones. Most web hosts either have a one-click install for WordPress or give detailed instructions on how to install it to their servers. And once you have WordPress up and running, you should be able to install ProofBuddy by just uploading a file and activating the plugin.
That’s not to say there won’t ever be a version of ProofBuddy made for other content management systems, but we don’t have any plans right now.
