I did it not because I like to hear myself talk, though of course the chance to hold court on a number for subjects for an undefined amount of time is, of course, enticing. But mostly, I did it because one of the things I truly appreciated when I was doing my PhD was personal histories. It was, I thought, incredibly interesting and important that you could sit down and read or listen to people who had experienced a different time and life. I'm fairly sure that whatever I do with my life, or whatever happens to me, that I'll be forgotten two hundred years from now, if not much, much earlier--but that researcher, or whoever, who is searching through people who were alive now has the chance to come across my interview, to hear what I said on issues such as immigration, generation change, and the like. My opinions, for example, will likely be incorrect at times, vaguely stated at others, and fine again another time. But it will be for someone else to listen to in the far flung future, someone who can write about the past, the people in it, and the influences that the time had.
The project is still looking for people to take part and, honestly, I fully recommend. Just follow the link at the top of the page.
