A good comment from George Couros: "This is what is so hard about social media in education. If you are too intrusive, kids will block you out (could be literally or figuratively), or they will move somewhere else." P.S. he needs to give his meme-posts a second thought. Today's, for example, neds a good edit. He posts: "In education, our learning not only impacts our own growth, but the growth of others we serve." Too many words. He means: "When we learn, others learn." Fewer comfort words (like 'we serve'), but more punch.
