I'm sure it depends on the startup, but I was perfectly happy to get code samples instead of a github link.

In that case, though, you should work a bit to demonstrate your engagement with the field in some other way. The kind of people who I most want to hire at a startup are the ones who would still be coding on something even if that weren't the job. I strongly want to avoid clock-punchers who only program because that seemed like an easier job than dentistry.

Note that a blog isn't the only way to show your engagement. A bunch of good Stack Overflow answers. A very thoughtful cover letter. A link to some personal tech project you did. The presentation you did for a local user group. Mentioning the time you spend volunteering with the FIRST Lego League.
