I appreciate your intent, but this tool needs a lot of work -- maybe an entire redesign -- before it would be suitable for the purpose you seek. See discussion at [1].

Besides, in my experience, only a tiny fraction of HN comments can be interpreted as falsifiable predictions.

Instead I would recommend learning about calibration [2] and ways to improve one's calibration, which will likely lead you into literature reviews of cognitive biases and what we can do about them. Also, jumping into some prediction markets (as long as they don't become too much of a distraction) is good practice.
