I know a few people here do this and I'm curious as to why. I have a certain amount of interest in it myself, but I've never considered really getting into it. The other day at work a co-worker was asking me about buying a laptop (knowing where the power button is qualifies me as an expert) and I asked what he wanted it for, told me that the wanted a more speedy machine, but it would be near solely used for researching his family history on the internet. Seems a lot of people are fascinated.
The BBC have been showing a programme where they research the family histories of celebrities called 'Who do you think you are?' Which seems a little odd for a title on this subject to me. What is the interest? I'm not critical, and I'm certainly not worried about 'ancestor worship' (as one of my friends regards the practice) but I wonder how much we believe that our ancestors shape us, and their stories define us, or whether it's purely curiosity about those that have come before.
Anyway, I'm off to Barcelona for a few days. Hope to see some good input when I get back. Have a good weekend all.
