Research into Social Media

I have recently been interning at Carpenter and Company, a marketing company specializing in non-traditional media to build and promote a brand or company. I have been doing a significant amount of research regarding social media and its uses in marketing and growing a customer base. I have a facebook, a myspace, and a linkedin account, and utilize all these things to help get a better understanding of the atmosphere regarding marketing using these tools. I have just recently discovered the use of rss feeds and widgets as well, which can be used to cross promote onto my other sites.
