Tracking a few different approaches that I have taken to resumes.
An HTML resume laid out as a timeline moving from left-to-right.
The World of Warcraft character builder style resume that shows skills in two broad areas. In general, the lower entries should be more difficult than the higher entries.
My LaTeX template.
Feel free to use the ideas in your own resume.
I have not kept my resume particularly up-to-date, so the different formats may have wildly different data. My LinkedIn profile is probably the most up-to-date despite the hours I've spent developing nice-looking, interesting resumes.
