I've written before about the importance of managing your online presence, as well as having good clips for when you're applying for a job. One way to address both is to post your résumé and clippings on a personal website.

A post on Freelance Writing Tips outlines the basics of putting together an online portfolio. If you don't know how to build a website (as most of us don't), you can use a service like Writer's Residence (run by the post's author), where you can create an online portfolio by filling in a form, or a blog tool like Wordpress.
