You may want to pay attention to Berkland. He seems to be the real deal. At least closer than anyone else in his predictions.
Berkland isn't the real deal; you're real gullible, though.
The perception of Berkland's "success" rests on the lack of understanding of the public of just how common quakes are, and the inability of the public to understand basic statistics and probability. Even someone with no predictive skill who makes a LOT of VAGUE predictions will have a few hits, and they'll promote their hits and ignore their misses.
