Stats from my Social Media Class

I'm taking a class from University of San Francisco to become certified on Social Media and Google Keywords. These stats were given by the teacher and social media guru, Jim Kukral.
1. 60% of people interact with companies with a social media presence
2. 93% say companies should have a social media presence
3. 85% say a company should interact with customers via social media
4. 56% feel better served by companies with a social media presence
5. 43% say a company should use social media to solve customers' problems
6. 41% say a company should use social media to solicit feedback from customers

What does this all mean. Social media is now as mainstream as any media. It's now the "obvious" media.
