Recipe for Reminder
What you have discovered is a recipe not for memory, but for reminder. And it is no true wisdom that you offer your disciples, but only the semblance of wisdom, for by telling them of many things without teaching them you will make them seem to know much while for the most part they know nothing. And as men filled not with wisdom but with the conceit of wisdom they will be a burden to their fellows.
This damning of writing (in writing) from Plato's Phaedrus is the exact reason why I benefit from writing.
Memory requires reminding myself over and over again about what to remember. More often than not, that comes from writing about the same things over and over again. Posts reveal patterns of thought. These patterns give me more to write about. Soon enough that thinking/writing cycle reinforces memory.
Sure Plato, writing is reminding, but reminding can lead to memory.
Makes me think of a blog as a model of thought, a memory palace of sorts.
