Many have asked this question before. And even now in the wake of the Twitter tsunami and the insurgence of many other forms of social technology, it’s still uncharted territory for some and down right terrifying territory for others. Fear not. Marta Kagan, self-proclaimed social media evangelist and extremely creative presenter, created the first of two slide shows found below a little over a year ago to inform us on what the f*** this new medium is and how we can and should be using it. It’s a funny but seriously informative and helpful presentation. If you haven’t seen it yet, flip through and you’re guaranteed to learn a thing or two.

Of course, the first presentation was created a year ago and, as we all know, a lot has happened in a year. Take a peek at the second version which she recently created with updated statistics and tips. Comparing the stats alone is slightly scary considering only a measly 12 months went by. But don’t let them scare you, instead let the presentation inspire you to, as Kagan says, “hop on the f***ing train!”
