Squidoo is a Web 2.0 Social Media phenomenon that is rapidly gaining traction. Think of it as a combination of Wikipedia and Linkedin or as a MySpace for adults. With Squidoo, the user is able to rapidly create a page (called a lens) on any topic. This page can be about any subject they want - hobbies, interests, their organization, their profession, etc. There is no limit on how many lens a user can create.
The advantage to Squidoo is web traffic (and we are talking serious traffic here as Google loves Squidoo). It is not uncommon for a Squidoo lens page to appear on the first page of Google results for its title! If you are responsible for increasing Internet traffic to your organizations web site, you need to look at Squidoo. To see an example, here is a Squidoo lens that I just created for Microsoft Certifications.
