If you already have a well rounded resume in terms of relevant work experience and are just looking for a "piece of paper" to compliment it, then an online degree could well be just as valuable as a traditional degree. If you are using a degree as a starting block for your career then I think that an online degree would not hold the same value. If there's plenty of other meat in your resume for a potential employer to look at the source of your degree becomes less of an issue.
