All journals should include a correspondence section

Letters to the editor can provide useful scientific information and evaluation of published work as well as acting as an additional level of peer review. Furthermore, letters are good reading material, especially if they involve a debate between authors. Finally, letters are relatively short. Therefore, inexperienced career researchers can use such an opportunity to practice putting together a cogent argument. However, it is far from an ideal situation if letters are the only (or main) type of article on which to base an academic career.
