The studies I've seen about readability and legibility tend to focus on a specific set of metrics: size, not just the point size, but things like the size of the lower case letters as a proportion of the overall letter height, and line length. People simply can't read really small type set in really long lines.

We get used to things, and we like reading the way we're used to reading.

Simplicity, wit, and good typography.

Most processes leave out the stuff no one wants to talk about: magic, intuition and leaps of faith.

Part of maturing as a designer is discovering what you're good at.

The truth about logos is that they are not that hard to do.

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.
