Google is not sufficient, I take it?
No; I just tried the query "consumer electronics site:predictionbook.com", and that only returned 1 hit; I know there are more (including one I just made and another I just voted on). It really is the lack of user-supplied meta-information that prevents useful querying, not the lack of a UI for doing so. The UI encourages predictions to be written very tersely, and doesn't supply an extended-info field when you make a prediction.
PB.com is quite possibly the least well executed idea out there that I keep not giving up on. :)
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?
