From my experience dealing with IBM, I can only imagine this was the result of 5 different consulting teams, assisted by 3 different outsourced development groups, which was delayed numerous times, then Watson was added, and then a re-org caused by layoffs, which finally resulted in a website that couldn't scroll and caused the CPU of my high-end laptop to scream...
You missed the most important part; it was initiated by a team of lawyers who were tipped off by another team who noticed the Watson design team were using a typeface on public websites which they didn't have the copyright to, and certainly didn't have the license to redistribute. Almost 2 years later, Plex was born. (This is a true story, by the way.)
Or so I thought, because I'm fairly certain everything we did in the 1990s has been thoroughly erased by ridiculous document retention policies.
