Credit Crunch?

So I keep hearing that credit markets are tightening up, and that loans are more difficult to come by. I personally don't know, as I'm not in the market for a loan and have a sneaking suspicion I can get one anyway. Maybe this applies to business credit, real estate, and car loans. I honestly don't know. Half of the financial press these days seems to be filled with speculation about what might happen instead of hard data about what is happening.

However, I find it difficult to believe it's hard to get credit when the grocery store has taken to printing credit card applications on the bottom of the receipts.
