I recognize Jon Skeet, Quassnoi, Alex Martelli and cletus... but I know them all from Stack Overflow. I wouldn't say all of those people are famous anywhere in particular other than there?
Alex Martelli I recognise; he's a python guru (behind the Python Cookbook, among other things) now working at google. There's a couple of excellent tech-talks on (mostly) advanced python by him that are well worth watching if you use python at all.
