The Connectbeam Blog has an interesting post today, it's title: Should Facebook Be Banned from Work? Gardner’s Nikos Drakos versus Ray Valdes. Given the fine reputation of the Gardner Group, I recommend you link over to Connectbeam and read up on this issue. The problem of access to web 2.0 / social networks is one facing many corporations. While there is obviously content on YouTube and Facebook which is detrimental to polite society and not work focused (or worse), many companies now use YouTube for marketing. I actually found a great professor, Jake Blanchard, via one of his YouTube video / tutorials. He now teaches MatLab courses for my company.
