I haven't read the Black Swan. I skimmed a few places and know a Taleb fan who has read both Fooled by Randomness and Black Swan. With moderate confidence I'd say FbR is the better book - Black Swan seems to be much of the same material presented for a wider audience. I thought FbR was excellently written, regardless of the content.
It would be cool to track some history / time spent on different things. As it stands it does not seem differentiated enough from the native timer (or a watch, for that matter).
