Rough term for an event where PowerPoint presentations are occurring in multiple rooms. You might call it a conference, but really it’s a powerpointalism experience. The definition of a conference —a formal meeting for discussion — doesn’t really apply since only the people up the front are talking and everyone else is listening. Generally, you want to be involved.
Note that powerpointalism can also be a noun “I’m experiencing powerpointalism” or more simply, setting one’s status to “powerpointalism” explains your current status.
Note that powerpointalism is how you experience marketecture.
Compare with PowerPoint Waterboarding which tends to occur in much smaller groups that you can’t escape from.
With reference to @aneel during Cisco Live Conference in Las Vegas, 2011.
