One part of the learning experience in solving a number of issues, but also providing an information luxury, is the effective recording of predictions that are validated for authenticity.
This can occur on a few different publicly viewable levels. First is simply public, and probably the most used. Next is publicly released after certain conditions have been met such as the author's death, and/or the prediction coming true or not, etc. Further is privately shared predictions, that can also be released to specifically shared people/groups after specific conditions (triggers) are met.
