In the 1960s, Deligne and Mumford compactified the moduli space of smooth curves by adding nodal curves at the boundary. We will look at the analogous question of compactifying the moduli space of weighted projective lines. Our interest is mainly in the various commutative and noncommutative degenerations that can naturally arise. This talk is about preliminary work done in this direction with Abdelgadir, Okawa and Ueda.
