I commend each of the individuals for caring enough about society to try to make a positive change in it.
I am curious of the background of most of these individuals. Certain social stigmas would have us believe that they are most like what some of us would call "nerds." That they enjoy playing video games, reading comics and living in their mom's basement. That's what we usually associate individuals with who dress up like super heroes and wear capes.
Overall, I do think that giving these individuals the spotlight is a good thing. Individuals need to realize that they can make a difference in this world, weather it is on a small scale or large scale. It all adds up to something.
My only concern would be, what happens when somebody gets seriously injured, and what fallout could potentially follow after that?!?
