Philip Olson has a few recommendations for the PHP project and community on how they can get more people involved in the different areas of involvement whether it be in two area he mentions specifically - development or working with documentation.
Unlike PHP.net, Ubuntu.com prominently displays "Get Involved" on their main site. This area clearly breaks up into different categories like Bugs, Brainstorming, Design (UI), Support, Localization, Testing, and the two I'll focus on: Development and Documentation.
For each of the subheads he outlines a resource that could help to develop that area and gives examples of each from the Ubuntu site - documentation, development. He's also looking at ways he can help change the current state of the "marketing" on the PHP.net site with a series of Open Source guides (on open source topics and open source themselves) to help bridge some of this wide open gap between developers and PHP.
