Comments cause me to stop and think and see things from another perspective.  They also rile me up and sometimes make me laugh really hard.  The beauty of blogs and social media is that it gives a social life to those of us who are confined to home, spend a great deal of time in hospital, and maybe life circumstances don't allow a "social life" outside of online.  I love reading blogs and others viewpoints to keep my mind sharp, take a break from thinking about the health crisis of the day, and having adult conversation (albeit in a comments thread) because otherwise I am lonely.  I consider my blogroll - my friends.

What I love from my own blog is the comments that come from left field - a parent that is struggling and I put into words what he/she is feeling and gave them a release.  Comfort is brought by to many by words and they are powerful sources if used correctly.  

Nothing self absorbed, narcissistic, or ADD about that.  Perhaps the commenter needs to view the world from another lens and realize we are not able to get out and party like rock stars with the real world.
