For start ups, I would much rather see someone with a track record with finished projects. Programs, code, apps, open source contributions, references from people you've worked with are all the things I look for as far as skills.

A blog is nice, because in an interview process, I only really get to know you for like 1 hour tops. In a blog, I can better understand your values, your interests, and what you've done.

Resumes have their place, if you have hundreds of potential candidates to go through. If you are a good candidate, you should have pages and pages worth of experiences, and it's now a matter of picking the experiences relevant to the task.
