One of the more useful visualization tools editors and stewards could have is a comparative map of the subjects covered in signals and forecasts. In particular, we'd want to be able to do the following things:

Gap analysis of signals-- show subjects that are heavily-represented in the forecasts, but under-represented in the signals (an indicator of the need for more signals on that particular subject).

Gap analysis of forecasts-- show subjects that are covered by lots of signals, but not discussed by forecasts (an indicator of the need for more analysis of that particular subject).

Signals that aren't liked to forecasts.
