Hi, Squidoo is a Web 2.0 content management system. Basically, you can put up any content you like as a lens. There are many modules you can use such as RSS feeds, Guest/Comment Post, etc. You need at least 3 modules there in order for your lens to be live. Treat it like a mini-website. You can build it in many ways and use it to sell products or even for hobbies or just to share your ideas with the world. It is something like a blog that requires updating. The advantage of using Squidoo is that it is SE optimized and can rank well for low competition keywords. Read my free report to understand how to do well with such Web 2.0 pages.
