Sadly, there are too many to write. We discuss them when they happen but all too often it's someone who was hugely important in one particular tiny community or specialism or something, and who the rest of the world has mostly never heard of.

If there isn't a writer who knows that area or that field, then it's hard to cover and explain adequately. A few have come up in my time on the Reg who are worthy of coverage but none of the available team really has relevant expertise. :-(
