While kayelex gave you some good advice, let me clarify it even more for you.
Search engines don’t rank websites, they rank web pages. They don’t assign PR to websites they assign PR to web pages. They don’t index websites, they index web pages.
While Squidoo’s Home page may have a great deal of link juice, it doesn’t help you at all unless you get a backlink from there. It doesn’t matter which website your page is on, it only matters how well you have optimized and promoted your web page.
The only advantage that you might see from a Squidoo lens is that you are part of a community and if you become well known and well-liked within that community you may get a great deal of traffic and perhaps backlinks from that community. If you manage to get your lens featured on a highly ranked Squidoo page that would also be a plus. In the absence of those links, you have absolutely no SEO advantage with a Squidoo lens.
You can build a following on your own hosted website or as a member of a community like Squidoo. There are advantages and disadvantages regardless of which method you choose. With Squidoo you become a member of a community, you don’t own anything and you could be kicked out. With your own domain, you own it but you must join other communities or build your own.
If you are clever, you will figure out how to do both in a symbiotic relationship where each page supports the other.
