Smart ideas from a smart guy

In any large organisation you'll meet lots of people -- some of whom you think are smart and others less so. And working in public relations you'll quite often listen to one of those smart people make a speech, give a presentation or do an interview based on ideas from an even smarter person.
Very occasionally you'll get to meet that person -- the guy (or gal) with the original idea.
Over the course of my four years at IBM I saw a number of smart ideas filter through the business -- and I found that almost every time I could trace them back to Irving Wladawsky-Berger. Though he's now semi-retired his blog is required reading for me still.
