  • 1. Creating Quality Content with Open Source ToolsBy: Scott Nesbitt When you think of Open Source software, what comes immediately to mind? Probably Linux, and maybe applications like MySQL, PHP, Apache, OpenOffice.org, and Mozilla Firefox. Applications that have entered the popular consciousness, and others which can be described as the plumbing of the Internet. But Open Source is a whole lot more -- a wide range of utilities, applications, and tools. And a number of those tools are well-suited for creating quality content. This presentation will introduce you to the Open Source tools and techniques that you can use to create quality content -- everything from documentation, Web content, marketing material, collateral, or whatever your deliverable is. My goal isnt to convince you to throw away the software that youre using and adopt Open Source. If you want to do that, great. I just want to open you eyes and your minds to an under appreciated and under noticed alternative to commercial software for creating© 2008 Scott Nesbitt Creating Quality Content with Open Source Tools - 1
