Ryan Hoover on why blogging is the new resume:

When startups ask about my background and expertise, I respond with a brief bio and link them a few select articles I’ve written, relevant to their situation. If you read my writing, you will know how I think. If you agree with my analysis and recommendations, you will trust my product decisions. If you disagree, then we shouldn’t work together anyway. Resumes fail to communicate any of this.

I have landed any contract because of this little blog, but writing is a useful medium to allow your brain to process ideas.
