I belong to squidoo. It is a great community of lensmasters who write lenses and talk with each other. You can make money on squidoo too. Have a blog? This is a great way to get your blog some traffic.
It is a place to put all of your lenses onto one lens. It puts a small picture of the lens with the title for you to look at before you click on any one title. If you are a giant squid or not you will want to make a lensography.
