Marketing Sherpa offers listings of both people looking for jobs and job openings. The listings are mostly in advertising and marketing - with an emphasis on marketing of course.

Looking for something outside marketing?  The usual suspects have been increasing their listings on a regular basis:

http://www.careerbuilder.com

http://www.moster.com

An interesting place to look for free is Craigslist, which is a free classified site for over 50 cities.

Looking for a job site that is harnessing the latest Internet trend?  Jobster uses tags (keywords attached to different profiles) to help sort their database of prospective workers. If the tags are confusing, just click on the logo at the top and be whisked off to a traditional search box.

Good hunting!
