This infographic from eLearners focuses on the main psychological reasons behind Twitter, including who uses it (35% are between 18 and 29 years old), what they share (nearly 25% claim they don’t hold back and share most things or everything online), why they tweet (it helps fulfill basic social needs such as belonging and affection), and even how to grow your follower count (avoid negativity, use correct grammar and avoid using too many hashtags).
