Princeton researchers have created a website called All Our Ideas. It allows people to compare two ideas and vote on the one they think is best. So, for instance, the site asks, “What is our most important national priority?” You then click on one of two ideas. When you do, you’re offered another pair of ideas. You’re free to add your own suggestions, too.
Someone has set up a page there to ask Who Was the Better Roman Emperor? Very amusing but I am not sure if I can really say if Florianus was better than Galba. Other votes were easy. Augustus beats Caligula hand down.
