I actually used squidoo when it first came out, and very few were on it. But I don't think I ever made any money. I'm sure you can, but just like anything you have to spend alot of time to make alittle back.
Squidoo is now making me anywhere from $300-$600 a month and I've been using it for about 4 months. I've run other websites, blogs, and forums for several years and it's been the best platform for generating solid links as well as ranking highly and quickly that I have found. The google slap that happened almost 8 months ago is long gone, traffic levels have climbed back up to pre-slap heights and beyond. It's fun, easy to use, and when done properly, wallops regular WP posts or ezine articles for SERP rank...
