If the "worth it" includes provable portfolio of skills, I don't know a better place than series of well-written blog posts.

Other "worth it" could be the development of your writing skills, documenting own learning path and so on. Maybe something can be even useful for you as well later on.

If you think "worth it" as a way to get attention, get job offers automatically e.g., likely not worth it unless it gets HN front page.
