Ask HN: Did you personal website help you get hired? Tell about it

Context: I'm a senior dev, well-employed, and hopefully won't be looking for a job anytime soon. I'm just working on a blog/website as a hobby side-project, and really could use some external motivation to keep going (instead of scrolling through social media and watching TV). Also I can't decide what to write about, and whether to make it more nerdy or more professional.
