Squidoo is an enormously popular and well-regarded site that has been around for a long time already. Many people have used it to make money, and it's also a great way to build links to other websites.
The Squidoo structure has been used as a template for other sites. These include Wizzley and WebNuggetz. The latest of these is Zujava.
These all look pretty well run and are worth investigating.
