comment half-plane percolation clusters
Very nice question. Are there reasons to believe that the behavior for the half plane is different than the behavior for the full plane?

This answers belongs to the mathematical jokes question not here. (A good joke though.)

comment The shortest path in first passage percolation
That's very interesting. I did not know that there is a (provable) lower bound for xsi and this certainly looks very relevant. (In fact stronger than my question...)

comment Correlation and Causation. When can we believe correlation (reasonably, at least) imply causation
This is a very important question in applied mathematics/statistics. People indeed tried to suggest various mathematical criteria for causation. I find it hard to understad why people regard the question as borderline or even want to close it.

Many interesting answers. Of course, this is a very individual matter without a correct answer. Anton's answer was especially surprising and useful.
