We discuss the cosmic string scenario of large-scale structure formation in light of the result that the strings are not smooth but instead have a lot of sub-structure or wiggles on them. It appears from the results of Albrecht and Stebbins that the scenario works best if the universe is dominated by massive neutrinos or some other form of hot dark matter. Some unique features of the scenario, such as the generation of primordial magnetic fields, are also described.
