How does social media impact how you lead, mentor and communicate to your team and should social tools play a role?

What are the pros/cons of this? First just a bit of background: throughout our lifetimes and careers, technology has advanced at an exponential rate; it has rapidly changed processes, the way we interact, the way we problem solve, and the way we do business. Social media is a relatively new phenomenon; however, to say that it is a "game changer" is an understatement to say the very least... So, how has this changing dynamic impacted your leadership style? How do you see it changing the way we communicate, interact, problem-solve, and do business in the future? As we've seen right here on RallyPoint, collaboration at this scale (and with this level of diversity and knowledge) is extremely powerful!  The idea here is to generate thoughtful discussion, brainstorm and have some fun in the process. So, in your opinion what applications does social media have in the military realm?  Now, let's get this thing started, so grab those keyboards and... see you all in the discussion threads!
