Videoconferencing
Never tried videoconferencing before: I don’t really see the point[1]. But my mum’s just got a new macbook, and upgraded her skype, and wanted to play with her new toy!
So she skyped me. And as soon as I replied, I could see her in a skype window. Looking at it, there was also a button to turn my camera on. Hey presto, we’re videoconferencing!
[1] Now sharing something on screen (“whiteboard”-style) is another matter, and makes a lot of sense when discussing something complex. And yes, I can see the plain ol’ video has a point too when there’s something visual to demonstrate. But not just for its own sake.

Maybe not when it’s someone you know really well on the other end. The first time talking to cow-orkers around the globe it helps putting a face to the voice. And I know my little nieces like videoconferencing as well because it’s much easier to understand who’s on the other end if there’s a face as well.
