A Christmas open house during the recent holidays brought home the social media divide among adults. I was pondering the fact that in the last two months I hit 400 Facebook Friends, about 1,024 Twitter followers (it tends to fluctuate a bit) and 1,040 LinkedIn connections. But at the get together, I was confronted by several adults in their 50s and 60s who had no clue about how to get value from social media – and most of whom were IT professionals.
