Peter Schiff's analysis of Janet Yellen (40 minutes, he goes over her forecasting record)
Summary:
-She (and other Keynesians like Bernanke) did not see a housing bubble.
-She downplayed the concerns of people who thought there was a bubble.
-She even pointed to data suggesting there was a bubble then used that data to conclude that there was no bubble.
-She said that she would have
negative interest rates if she had her way. That means you borrow $100 and only pay back $95, which would invariably lead to misallocation of capital in the form of highly speculative investments, leading to a massive bubble, followed by another legendary market crash.
Then there's always the data showing that Keynesian economics simply doesn't work:

The countries that went with austerity (spending cuts and deflation) are recovering much faster than the countries that took the Keynesian route of trying to spend and inflate their way out of debt, because that worked so well for Zimbabwe and the Weimar Republic.
The general consensus is that Yellen will likely continue QE, and possibly increase QE. Some things you can expect in the future:
-Continued 1970's style inflation.
-A growing disconnect between the economy and the stock market.
-Stagnant economic growth because inflation kills consumer spending. I can't order a new car if half of my income goes to shit like $6 gas and $3 loaves of bread.
