In August I wrote about using PredictionBook as a substitute for weekly reviews. Several months later, I am rather predictably not using it, for the same reason weekly reviews stop working: it reminded me of something I endorsed doing but didn’t finish, and that put an ugh field around the whole thing.
Weirdly, I re-picked-up that thing a week ago. This was completely independent: I haven’t looked at PredictionBook since September. I don’t think this has any bearing on the viability of predictions substituting for reviews, it’s just a cute coincidence.
