From a business perspective, social media is all about marketing. It's another way to directly impact proliferation and sales of your product by engaging and interacting with your target audience (in this case, apps), but it can work for most any business. Social media means unique channels where users can directly communicate with others (one-way or two-way), via direct message or chat, Facebook wall or newsfeed posts and notifications, tweets and re-tweets on Twitter, LinkedIn, the old-fashioned (but still heavily relied upon) e-mail, and other social platforms — both general and targeted to a specific niche.
