The art of conference calling. Wait. You didn't know it was an art? It's definitely a skill worth building if you're running a modern business, and it is as much an art as any other form of presenting. Whether you want to blame it on technology and the internet, or the costs associated to flying, or even the huge slowdown in flying America took after 9/11 that forced us into doing more calls, the conference call has become a huge part of doing business and you can't escape it.
