I put together a simple resume website experimenting with ways to add context to skills on resumes. I list a number of projects, and when you hover over each project then the corresponding skills in a word cloud change color and enlarge. In my mind it does a much better job than a paper resume as clarifying which skills are actually in active use and which are paper skills.
I like it a lot, but maybe you could have a dedicated area for the job descriptions on the right side, just above the keywords? Right now, it is very difficult to scroll through the list of technologies used because the location of each job title moves back and forth while moving the mouse down.
My example is at http://willarson.com/ , but its simple to make your own ( http://lethain.com/entry/2008/oct/18/r-i-p-your-resume-site-... ).
