Basically on squidoo you create lenses which is really like a mini web page. You can create lots of lenses and these can be on any subject you like. You have the option to add several features, for example you can add a site list, products that may be of interest to people, suggestions to other lenses etc. By adding products via amazon and eBay etc you are able to make a little commission if people click through your lense on the product. Thats kind of what i have gathered from it and im sure there will be others that can tell you more.
