sortega comments on What are good alternatives to Predictionbook for personal prediction tracking? Edited: I originally thought it was down but it was just 500 until I though of clearing cookies.

My main use case for prediction book are private personal predictions and, secondarily, predictions for a small group, also private. I think using markets for the group predictions is also a good fit but AFAIK there are no private groups in manifold yet.
