"The only purpose I'm doing it is for SEO, for links coming from those social networking sites."
Adding content is the best advice for getting links. I used to add my site to directories and social networks for a quick boost in seo, but that just fades out after a few weeks anyways. I guess if your site is new its not a bad idea to do this to get indexed fast. But.....
I get new links all the time from my new content and people adding a link to my page as a referral to what they wrote on my subjects and content. Thats the best practice in the long run.
