How did the idea to create WordPress come to you and why did you decide to make it a free product?
WordPress evolved out of my own desire for a blogging product to make my site better, and a frustration with the existing solutions that I felt were too complicated and hard to use. WordPress was built on the code of an existing GPL product called b2, so it was completely natural for it to continue the GPL license and preserve the freedoms of our users.
How do you make money on it now and what do you plan in the future to earn more?
About 5 years ago I founded a company called Automattic to create commercial services around WordPress that would help grow the market. The first of these was an anti-spam service, Akismet, and we later followed up with WordPress.com, Gravatar, Polldaddy, IntenseDebate, VideoPress, VaultPress, and more to come.
How does your development process work: how many developers do you have, are they full/part time workers, are they located in an office (where?) or are they remote? What IDE and environment do they use to work on WordPress?
There are about 200 active contributors to core WordPress development, all of them volunteers although some are paid by their employers (including Automattic) to contribute to WordPress. There is no set development environment, everyone uses what is most comfortable to them. I have noticed a a definite bias toward using Macs, though.
WordPress is definitely one of the largest publishing platforms now, but there are excellent competitors including Blogger. Innovation in the market is good because it keeps us all on our toes.
Starting from 2.3.3 version the biggest part of changes were connected with admin area and look-and-feel, and not with the code optimization. Can we hope that one day the engine will become more robust?
We are constantly rewriting, refactoring, and optimizing the code in WordPress, ofter as much as 10-20% in a single release. Since 2.3.3, probably 95% of the code has been rewritten. This deliberate process of improving the code is better than a massive rewrite because us to test each change more and preserve backward compatibility.
Do you plan to stop to support PHP4 and avoid deprecated.php usage?
Yes, in 2011.
Are there any plans to make plugins approval system more tough? Some public plugins still are of poor quality.
Do you reward the plugins and themes developers?
I’m sure many plugin and theme developers are highly rewarded by their work, but we don’t give out money or anything from WordPress.org.
Will you add some more plugins out-the-box apart from Akismet and Hello Dolly?
What do you think on WordPress turning from a blog engine into a full featured website CMS?
This is a pretty natural transition that started with the introduction of the Pages feature and has grown from there. More than half of new WordPress installations aren’t being used as blogs at all.
If you start to write WordPress now from the scratch – what would it look like?
Starting today I would probably leave off some features that aren’t used as much anymore, like a blogroll manager, and focus more on SEO and social integration.
WordPress itself is a framework you can use to build highly advanced and scalable applications.
Which CMS/CMF do you like? What projects did you keep in mind while creating WordPress?
Our about page mentions and links to Textpattern, Movable Type, and Drupal as inspirations
Thank you, Matt!
