A couple of weeks ago, I posted on the effect a down economy has on a client's willingness to buy what they perceive as "risky" (you might refer to as "good") creative work.
For another take on the same thing, check out this post on Please Feed the Animals. He's reporting on a New Yorker article from James Surowiecki (author of The Wisdom of Crowds). All these are good reads and provide more context for what's going on and how, managed right, the depression can provide an opportunity.
