Social media is a tool, useful for business and self promotion. Also handy for checking up on what friends and relatives are doing.<p>That said, I agree with Stephenson (I really enjoyed his latest book Seveneves) that it&#x27;s use can get in the way of doing more creative and productive things.<p>I am a big fan of &quot;self monitoring&quot; to keep track of types of food eaten, time spent on social media, TV, etc. Personally, if I spend more than 15 minutes a day on social media that is a warning sign that I need to do better time management.
