Also, for who are not in the know, Simon Peyton Jones is a well respected computer scientist, mostly known for his work on developing the functional programming language Haskell (together with others ofcourse), Haskell research is funded for a large part by Microsoft I think.
Also, to add what others have said, he is one of the best speakers I've ever been lucky enough to see in person: SPJ, Philip Wadler, Guy Steele... good company.
(I probably shouldn't be making any handwriting/typography comments.)
This is a very funny question, why I use Comic Sans. So. All my talks use
Comic Sans, and I frequently see little remarks, “Simon Peyton Jones, great
talk about Haskell, but why did he use Comic Sans?” But nobody’s ever been
able to tell me what’s wrong with it. I think it’s a nice, legible font, I
like it. So until someone explains to me — I understand that it’s meant to be
naff, but I don't care about naff stuff, it’s meant to be able to read it. So
if you’ve got some rational reasons why I should not, then I’ll listen to them.
But just being unfashionable, I don’t care.
