I've reached the point in my writing career when I find an old blog post on some deep technical topic, and have absolutely zero recollection of writing it lol
@geerlingguy I have a similar experience when googling or searching on reddit for some problem - I find a result, read the problem description, find it describes __exactly__ the thing I'm trying to solve, and see there's no answers. Then check who posted the question, and it's me from like 3 years ago.
