If you've never seen anything like this, check out www.squiddoo.com. I created a "lens" at the urging of a business associate, and it's quite interesting to see the "experts" on various subjects.
For me, I've set up a lens titled, "Getting Ahead at Work," and filled it with career advice from various sources (including myself), interviews, helpful career books (including my own) and other Web sites (did I mention I included my own?)
The Squiddoo "Lensmasters'" interests range from Audrey Hepburn to cats to woodworking to engineering...there's something for everyone. Have a career you feel passionately about and would like to share your expertise? Or, have a product or service that you would like to promote? Try this out -- it's a good way to get your presence known in the increasingly competitive Internet world. Just make sure you do your homework and create something that reflects positively on you as a professional.
