I love Squidoo.com.
I've been building a collection of lenses on some of my favorite topics since Squidoo was still in beta.
Are you an expert on something?
Build your own Squidoo lens and tell the world. It's free, and you may even earn some money from it.
Do you have any lenses on Squidoo.com?
If so, here's your chance to let everyone know that you are a Lens Master.
