If I had to name one, I’d say ProPublica’s is the most important business series of last year (which come to think of it, may be one reason they got it in under the Pulitzer board’s Dec. 31 deadline), showing as clearly as we’ve yet seen how Wall Street intentionally kept the bubble going long after it would have deflated.

One question is how much, if any, of this could be prosecuted. For instance, I’d be interested to know more about what Merrill told investors about these specific CDOs—ones it created that were so bad the company had to pay its own people to take them.

Here’s hoping there’s more to come on this in 2011.
