Sid Steward is a programmer, writer and entrepreneur. He maintains the PDF Toolkit and wrote PDF Hacks. When he's not working on PDF, he's creating goodies like LookLeap (a better TinyURL), GoJot (social bookmarking meets site commenting), and The Punch Poll. He continually battles entropy and will gladly tell you about G del's incompleteness theorem. Bjarne Stroustrup is one of his heroes. Feel free to contact Sid.
