Honestly people who post daily with no traction seem more crazy to me than the people who feel defeated after day number 7 and just stop posting. It's totally human to feel bad when talking and nobody stops to listen.
I know some people treat blogging like a journal instead of a showcase. Writing to their future selves instead of a general audience.
In terms of getting traction for employers, posting in small communities with people you are acquainted with seems like the way to go. (@people-other-than-OP, I talk about that more in a different comment)
I'd say there's an initial learning curve of the basics that isn't bad. Kinda like learning programming for the first time; it's a different way of thinking and for something like Sudoku I'd say it's even pleasant.
But when you try to write a CLI videogame, or anything with an evolving internal state, then Prolog stops being the elegant logic system and instead becomes big bundle of edgecases where nothing makes sense practically or theoretically.
