Bio is probably empty because for a certain age of HN readers, he's already well known and regarded, but over time as the HN population grows it's obviously less likely to be the case.
I'd argue that age isn't even relevant. I'd say that there's a significant overlap between readers of "The Cuckoo's Egg" and HN folk, whether young or old.
Makes me feel even older, Benji. I wrote it when I was 38.
Now, at 75, I'm astonished at how much has changed online. When I first started fooling with the Arpanet in the early 1980's, I calculated that I probably knew around 0.01 percent of everyone on the net. (where "knew" meant something like "have heard of" or "saw at a meeting") ... that number impressed me with how big the network was.
Today, what percent of the network users does a person know? 1 / 10^-7 or so?
