Some suggestions (desperate pleas, even)
* A way to see all replies to your own comments or posts * Setting defaults for sorting rather than having to manually sort by recent every time * Put the see all comments link in a reasonably easy to find place * "All posts" which actually shows all posts...
My response to the smoking lesion question is:
If the lesion doesn't affect your ability to reason, then deciding to smoke as the result of a reasoning process isn't correlated with cancer, even though deciding to smoke in general is, so you should smoke.
If the lesion does affect your ability to reason, the question is ill defined because it may not be possible for you to execute some strategies, or only possible to execute them with some probability.
Of course "as the result of a reasoning process" needs to be phrased more precisely (every decision can be said to be the result of some reasoning process). Maybe "when you make some particular deduction, compared to a counterfactual world where you did not make that deduction".
