Lots of people Twitter these days, myself included. But following some of the Twitter impostors can add a humorous twist to your Twitter (that even sounds funny!) And now you can follow Ben Bernanke (or someone who is pretending to be him). http://twitter.com/benbernanke
Whoever this is, they have a MUCH better sense of humor than our beloved Chairman. You can also follow the Federal Reserve directly, which might give you more insight, if you are into this sort of thing.
