I love Squidwho. I think the layout is great and it is easy to make a lens look good.
Tonight I made a lens originally with the intention of promoting my audio book store. There you can download audiobooks and have them ready to play within minutes. You can load them to an iPod or burn them to disc.
I made my lens on the controversial Dr Laura Schlessinger. Squidoo is great because as a website owner, I can use Squidoo to build links and traffic to my own websites, but at the same time, I can monetize the website with Squidoo's built in system.
