1guydesign.com is a testbed of sorts for my work in Open Source applications, a landing place for often odd snippets and posts on things which relate to projects I'm involved with and occasionally.. a free, downloadable bit or bob.
Currently, it's roughly crafted around a few pieces of GPL software I develop, a8e and mojoblog.
Kevin Murray is 1guy, not THE one guy but 1 guy nonetheless. This is his sandbox, where he adds notes and posts on open source technologies, w3c compliance, joomla, wordpress and mojoBlog tutorials and an occasional gripe about spam.
