I'm in; pleasantly surprised.
This bit from the final registration page is interesting - "But one other requirement for forecasters has changed. We can welcome those who are not US citizens." Implying that at some prior point non-US citizens were not accepted.
A tournament is currently being initiated by the Intelligence Advanced Research Project Activity (IARPA) with the goal of improving forecasting methods for global events of national (US) interest. One of the teams (The Good Judgement Team) is recruiting volunteers to have their forecasts tracked. Volunteers will receive an annual honorarium ($150), and it appears there will be ongoing training to improve one's forecast accuracy (not sure exactly what form this will take).
I'm registered, and wondering if any other LessWrongers are participating/considering it. It could be interesting to compare methods and results.
Extensive quotes and links below the fold.
A general description of the expected benefits for volunteers:
Could that be any more LessWrong-esque?
