Whenever I meet someone with a name much more interesting than "David", the first thing I do is ask them how they pronounce it. And then I make sure I use it, properly, during the ensuing conversation.
Your name is a big part of your identity, and if you want to try and connect with someone, a good way to start is by using their first name.
Technology makes it especially easy to use someone's name when communicating with them electronically.
It also makes it easy to get it wrong.
