The 10/20/30 Rule of PowerPoint

I suffer from something called Ménière’s disease—don’t worry, you cannot get it from reading my blog. The symptoms of Ménière’s include hearing loss, tinnitus (a constant ringing sound), and vertigo. There are many medical theories about its cause: too much salt, caffeine, or alcohol in one’s diet, too much stress, and allergies. Thus, I’ve worked to limit control all these factors. However, I have another theory. As a venture capitalist, I have to listen to hundreds of entrepreneurs pitch their companies. To prevent an epidemic of Ménière’s in the venture capital community, I am evangelizing the 10/20/30 Rule of PowerPoint. Ten slides. So please observe the 10/20/30 Rule of PowerPoint.

Presentation Zen Presentations Experts Warn Key IT Failures in Websites May Have Negative Effects on the Nervous System | Search Journal LONDON, December 12 /PRNewswire/ -- - Study Identifies the Five Key Factors of a Badly Designed Website That May Have Negative Effects on the Immune System, Cardio Functioning and the Nervous System According to a report published today by the Social Issues Research Centre and commissioned by Rackspace Managed Hosting, the UK's most recommended hosting specialist (1), there are five key IT flaws in the way websites are designed and hosted that may lead to harmful health effects. The study combined data from a YouGov poll of 2,500 people with physiological tests on a separate sample of internet users, who were asked to find information from a number of different websites. The tests measured the physical and physiological reactions to website experiences, looking at brainwaves, heart-rate fluctuations, muscle tension and skin conductivity. Results indicated that badly designed and hosted websites cause stress and anger, leading to the term "Mouse Rage Syndrome" or MRS being coined.
