Welcome to the Q&A Forum

I need to disagree with Alex.  If you examine the impact the Google Panda/Farmer update had, you'll see that sites like Squidoo and HubPages took major hits and lost significant ranking.  Why? Because so much content on those sites was considered low quality or of insignificant value to Google.  So why would you want to go after links from such places? If you've got a team of people working on a multitude of inbound link efforts, it might be a different story, but if you're not relying on a team of people to do the work, I would suggest your time is much more valuable than focusing on what are now low quality / questionable links.  Especially when we're now talking about what Alex suggests in "spinning" the articles.  To get spinning right, you really need to know what you're doing otherwise you are more likely to cause harm than do good. It's much better to consider finding places to write UNIQUE articles you can get posted to high quality sites - guest blogging.   Sites like MyBlogGuest.com can get you started along that path.  Getting just one guest article that has one or two links pointing to the appropriate most relevant page on your site, where the article is posted to a site where your target market visits, can be worth dozens or hundreds of spun articles spit out to places like Squidoo or Hubpages.
