I immediately signed up, as this is the kind of tool I could really use. There are a number of scenarios (especially financial ones) that involve uncertainty in my life, and I've been attacking them with spreadsheets and later Mathematica. But spreadsheets are too simple, and Mathematica is too cumbersome. Applying probabilistic programming tools is too complex: I would spend way too much time on details. So, this seems like just the right tool for the job.

Example scenario: should I pay off my mortgage, which is in a foreign currency?
