I worked for the consulting company that partnered with them to re-brand and re-code their web site in 2002, yes. It was long ago and while it was cool to have done a site that gets that much traffic, it was a run-of-the-mill consulting project, so no, there isn't anything written up about it.
That's one small step for a consultant, one giant leap for pizza eaters. While maybe not interesting from a technical standpoint it might still find a big audience among non-programmers.
