There is no consensus among academics about whether people should seek to make their publications least publishable units, and it has long been resisted by some journal editors. Particularly for people just getting started in academic publication, writing a few small articles provides a way of getting used to how the system of peer review and professional publication works, and it does indeed help to boost publication count. But publishing too many LPUs is thought not to impress peers when it comes time to seek promotion beyond the assistant professor (or equivalent) level.
