I am at PyCON UK right now. I have already had 4 conversations with people who badly want better json performance. (And one person who says zip performance bad, is it? I told him to write a bug report), and its only lunch time of day 1 of the con. Faster json thus appears to be an itch that needs a lot of scratching around here.
