Keeping up my streak of mildly entertaining, though basically useless Chrome Extensions, I have create a very tiny extension that keeps the Nate Silver fivethirtyeight predictions in your Chrome toolbar at all times.
You can choose which of Silver’s models is displayed, and clicking brings up more detail as well as links to a few other sites making predictions. Check it out!
For those who are interested in such things, the code is up on github. It’s actually a reasonably minimalist example of a “browser action” extension.
