The scientists at CERN were actually surprised that people commented on this. Reportedly Fabiola Gianotti, the coordinator of the CERN program to find the Higgs Boson, was asked why she had selected Comic Sans. She simply said, "Because I like it."

A lot of times, you design a logo to be timeless, but with something like the Olympics, timelessness is maybe not something you should be going for. Maybe you should be trying to come up with something that will really become associated with a moment in time, a few weeks, that happened, period. Then you look back, think about it and connect it with that time. It may look dated later but it will be still be evocative.

I'm not an expert in typefaces that serve scientific writing, but I'd guess that's another dozen or two.

Target for example, is just a dot with a circle around it, that's all it is, so if you want a logo like Target, you don't need to hire a designer, you barely need to know how to operate a computer program, the logo may as well be anything.

There was a time when most people had a choice between two kinds of personal communication, handwriting or using a typewriter. Today, people are invited to choose from a list of (surprisingly exotic) typefaces every time they turn on their computer. I think this has made everyone more aware of the idea that picking a typeface is a conscious choice.

Australia is one of the few places that I can think of where the cities, at least those I've been to, seem to have strikingly different characters and visual textures. To an American like me, there's basically Melbourne, Sydney and Brisbane and the rest is all bush.

In the US you have New York, San Francisco, Los Angeles, Boston, Miami and dozens of other cities; a few of them have a really strong visual character. But even with those there is just too much space between them and too many people.
