Basically, this article is telling us about what the chairman of the Federal Reserve, Ben Bernanke, said in a recent speech. These speeches are always important because they give us some idea as to what the Fed is planning to do.
In this case, Bernanke came out and pretty much said that the Fed needs to do more to stimulate the economy. He is worried about how much unemployment there is and he also fears deflation. In order to try to solve these problems, the Fed seems likely to put more money into the economy by buying government bonds and such things from banks.
The article goes on to say that not everyone is convinced that this is the right thing. However, it seems clear that the Fed must do something because there is not enough growth in the economy right now.
