Nope ... I think it is a wave. There was definitely a huge wave in the 80s. Ten of my friends left in one year and none of them have come back. I definitely notice these things even when they don't apply to me. When everyone else seems to be leaving and you are staying behind, you feel very left out and wonder if you are insane not leaving too.
I'm sure the other South Africans on this site have discovered the same thing ... there is definitely another major emigration wave on at the moment and the most popular destination seems to be Australia. You bump into someone at the shops, tell them you are leaving and they guess where you are going and say 'you too?'. This week I discovered that another family associated with the mommy and baby group that I attend is also off to WA courtesy of the same company and will also be leaving early January. Unfortunately they are not heading for the same town but are also destined for the outback. Looks like Australia's resources boom is going to be costing South Africa big time in terms of skills.
