1) Social media content is becoming more disposable as brands constantly churn out new content to engage online audiences. This leads to mistakes that can be quickly deleted but still spread online. 2) Brands are increasingly engaging in banter on social media as they develop more human voices. Examples include food brands joking with each other on Twitter. 3) As brand communities grow very large, they are subdividing into smaller interest groups to better engage members who joined for specific reasons. New social media tools allow more targeted messaging to these subgroups.
