What makes a social media platform valuable to go to?

A major reason I'm taking this class is because I'm developing my own social media platform. Over the past 8 months, I've done a lot of research and this is one of the questions I've explored.

Several weeks ago, I created a video articulating my findings.

The conclusion is a social media platform needs to be...

• Fun
• Relevant content
• Relevant people 
• Easy to use
• Does something new
• Has the right level of privacy
• Clarity on what is shared and with who
• Control over privacy
• It needs to make money (hopefully has a user friendly revenue model)

Each person has their own desires for many of these. So these principles would be vastly different across age ranges and peoples.
