Anthillz.com has just launched an online reputation site for professionals. Their taglines at the moment are "Share your reputation" and "Make a name for yourself", and the site's copy crrently lists the following reasons why a person would use the site to build their online reputation: "Share the good things people are saying about you", "Strengthen your professional relationships", and "Build a reputation that people know and trust". It appears to be a bit like LinkedIn's testimonial feature, but the entire site is focused on your professional reputation. It appears they've gotten around the tricky part of online reputation by only allowing trusted colleagues to leave a testimonial about you:
"The heart of your Anthillz profile is a series of testimonials and reviews written by colleagues you trust. Their words paint a rich picture of who you are and what it’s like to work with you."
This begs the question 'What about the people who have something bad to say about you?' For outside researchers, this type of information can be more useful than just positive praise.
