In its widest context a social experience is visiting a pub/bar with your friends. It could be attending a conference or seminar and interacting with people in a business setting. We know that social interaction is important and people are tribal and need social connections. The huge growth in social media is tapping into that basic human need.
A technology enabled social interaction helps to meet psyhological needs for: safety, love/belonging, esteem and self actualisation, and the resultant emotions evoked. Technology enables a wider, faster, more frequent interaction. thus creating in a digital social experience.
