Pretty much apropos of nothing (it is Friday afternoon, after all) I was having a look at the Computer Hall of Fame website, part of the San Diego Computer Museum.
They've got a list of potential inductees into the computing Hall of Fame.
My mind was suddenly cast to earlier this week, when there was talk about who had been voted the most important French great of them all.
Of course, the Beeb ran its programme on Great Britons a while back. A depressed alcoholic came top, narrowly ahead of a trainspotter and a bit of posh totty who "entered the nation's hearts".
But who would be your greatest technologist of all time? Would it be Bill Gates or Steve Jobs? Would it be Sir Tim Berners-Lee or Doug Englebart? Or even, going back, the likes of Ada Lovelace or Charles Babbage? I'm sure there are hundreds of candidates.
But, in your opinion, what person has made the greatest ever contribution to technology?
