It is explained that the following two problems are equivalent:
(i) describing all affine rulings of any given weighted projective plane;

(ii) describing all weighted-homogeneous locally nilpotent derivations of k[X,Y,Z].
Then the solution of (i) is sketched. (Outline of our joint work with Peter Russell.)
