For myself, my blog and GitHub activity were key points in my interviews that heavily influenced my previous two hires.

> Also I can't decide what to write about, and whether to make it more nerdy or more professional.

Personally, I use my blog to write about:

- Niche things I run into that I want to document for myself

- Things I’m working on that I think are cool

- Opinions on why I do things a certain way

I love reading other blogs that orbit around this type of content. One suggestion I would make is to focus on writing your blog for yourself instead of a fictional audience. That way your blog’s value is self-contained, rather than worrying about the value other people get out of it.

Good luck!
