WordPress
WordPress is free, open-source software that makes it easy to manage blogs and other web sites. Users can login and edit the content of the site just like they would edit their email, without having to worry about writing code and updating navigational pages. It began as a tool for building weblogs (personal sites with diary-like updates), but it has grown over the years to work well with other kinds of sites. I use WordPress to manage this entire site, and use it to build web sites for clients that they can update themselves.
Presentations
(1) I spoke at the D/FW WordPress Meetup in April 2009, giving a presentation on the techniques, page templates, and plugins I uses to power the multiple-author functionality on Journey to the Sea. Hopefully, this will be the first of many more opportunities to share with others from my experience working with WordPress.
(2) I spoke at WordCamp Dallas in June 2009, giving a presentation on putting WordPress custom fields to work on a blog. This page contains a video of that presentation, along with links to download the theme files I modified during the presentation and to other resources I mentioned.
