Hi there,
I currently manage my own Social Media company 'MediaPulse11', (Small Business) where I basically generate traffic to companies websites, and for some clients manage their their social network accounts.
Social Media can create a Real Buzz on just about ANYTHING. Tweeting brings attention to you, and your product. Most businesses don't have the time or staffing to keep up with social media, hence their sales suffer from lack of brand/product.
I also manage a twitter account with over 35,000 followers that retweet my tweets on average of 500 retweets and 600 favorites.
My WordPress Blog is current and I periodically on other blogs of special interests.
