A lot of social media really is an editorial approach. You have to have good writing skills and you have to have a passion for it. You have to want to do it everyday, ‘cause once you get in ain’tno getting out.

Social media has taken brand reputation out of the control of marketers and into the control of the audience, both in terms of good reputations and bad reputations.

In social media the value for users of having one inner operable social network is so great, that it’s very hard to believe within the next year or two of not having a fairly complete inner-operability and visibility across social networks.

One of the benefits that social media brings to the enterprise is a critical need to ensure cross functional communication systems are in place. As we're seeing social media does not live only in PR or Marketing or Customer Service.

Brand mentions are just the tip of the iceberg –somewhere between 5% and 30% of the relevant category conversation. You should listen to the whole conversation.

Social media is not just a set of new channels for marketing messages. It’s an opportunity for organizations to align with the marketplace and start delivering on behalf of customers.

Social networks are where consumers feel comfortable expressing their feelings—good or bad—about companies, products and services. Marketers, retailers and social networks have an opportunity to tap into this stream of information-sharing.

Content marketing wins over readers more than advertising. This means business bloggers have the clear advantage since blogs are the best way to communicate stories.

Inbound marketing is relevant today because as consumers, we have gotten better and better at blocking classical ―outbound‖ marketing .In order to reach us as buyers, marketers need to find a way to become part of the natural interactions we have when we are searching for information and products.

Informing is not the same as delivering information. Informis derived from the verb to form. When you inform me, you form me. You enlarge that which makes me most human: what I know. I am, to some degree, authored by you.

Social media is a whirling tornado of content and comment…. If the original content is the seed, social media is the wind that takes it out in search of fertile soil (or the animal that eats it up and… tweets it out).

Just be nice, take genuine interest in the people you meet, and keep in touch with people you like. This will create a group of people who are invested in helping you because they know you and appreciate you.

Want to build a great brand in social media (or anywhere else, for that matter)? Don't be a jerk. Social media has accelerated the rate at which public perception of your actions (your brand) can spread. It hasn't changed branding. Listen, learn, and do right by folks when they need your help.

The good news is that social media is something special. It's not just a marketing tactic (although social media marketing can be effective). It's more of a movement. A philosophy that brings brands and customers closer together through humanization of the brand and mutual respect

With social media..you’re going direct to the consumer. Social media is an extension of good public relations, but should be a company-wide approach PR helps manage and facilitate.

Previous installments of social media marketing and content marketing quotes: Part 1, Part 2.

First installment of social media marketing and content marketing quotes:

Adam Ostrow
As opposed to trying to attract millions of eyeballs and monetize them with ads, branded social networks are less about profitability and more about creating loyal and engaged customers that will ultimately create revenue in more conventional ways.

Amber Naslund
Social media is, ultimately, an endeavor that a business must take responsibility for on its own. It can't successfully be outsourced long term if the company is to truly and authentically steward its own brand.

One of the tenets of social psychology research is the prevalence of reciprocity: that people try to repay, in kind, what another person has provided.

Ben Parr
If a potential customer comes to your company’s website and sees an active blog with insightful posts on how your company’s product helps customers, reads detailed posts demonstrating your company’s knowledge, and comes across a few case studies, they’re going to be far more inclined to come to you for their needs.

Marketing with Meaning is less about "context" -or finding the best time to get in front of a consumer's eyeballs -and more about "content" -or creating something that people find valuable in itself.

Social media can be a bit like a bunch of people with megaphones blurting out their messages one-way. People will cover their ears (unsubscribe) and tune that out. Use social media to ‘listen’ to and learn more about your audience.

Now, so much of what we do happens online and we are less likely to see the customers face to face. It's a lot more global. It's more competitive. And people are more skeptical of marketing messages.
