Social media is a great tool for the distribution of content, but it is not a great environment for content creation. The people I work with have some fantastic insights, but those really only come about when they are in an environment conducive to thought and reflection.
And social media is not that environment.
Just as standing on a stage in front of thousands of people is not the best time to try to write a song, being in the thick of your social media feed with comments, images and videos flying by is not the best time to create material of quality.
Yes, there are some people who are good at live video. However, even that material is infinitely better when it is reposted later after some editing.
