Here is an example. What if you are an expert in one specific thing? What if you gained experience in “comic book collecting” and you want to share that knowledge with others?
You could start a web page or blog but you don’t necessarily want to commit to posting every day. There are Wikis but other people could contribute or distort your content and there is a bit of a learning curve until you learned how to code in Wiki style.
Here are some examples of Squidoo Library Lens
The reality of using Squidoo is that there are some people who know their topic very well and have the talent to write about their subject. There are others folks that put up the bare basics of information but have a lot of affiliate links. Many of the lens are abandoned or never started because the person truly didn't understand the amount of work it would take to make a quality expert page.
Squidoo also has to compete against other information sites like Wikipedia and all the other wikis in cyberspace as well as the beloved Google, About.com and a couple of million blogs. Take a look and tell me what you think.
