What Do General Officers Do When You Tell Them Their Social Media Presence Needs Work ?

They apologize and seek to improve.  Some time ago I was watching the McChrystal YouTube channel and studying his leadership videos.  In my opinion, they needed some work and some updating.  I wrote General McChrystal and made a few suggestions.  This was his response.  How one accepts constructive criticism says a great deal about that person's character (in my opinion).
