Squidoo is a very cool site where one can build their customized "lens" on a particular topic. Check out this back to school example designed by an author of parenting books. I have the "Lens of the Day" sent to me via email and this was the selection for yesterday. It's probably the best one suited to my needs and interests that I have received yet as it's fully developed with helpful links and tips regarding the back to school season. I also love the interactive, Web 2.0 features on Squidoo including a rating system, RSS feeds, meta tags, and a comments section.
