I think blogging is one of the best ways to market yourself and show the world your ideas. It’s also a great way to get your resume or cv in front of people.
Since I started the latest incarnation of this blog, I’ve had over 450 views on my resume. When is the last time that you handed out 450 copies of your resume?
So… get out there. Show the world that there is an amazing thinking bright human being inside you. Give it time, work hard, and people will notice.

I find the other direction works too – when someone has a website URL on their resume, it’s a great way for it to stand out from the pile.
I’m working on a TiddlyWiki vertical for authoring hResumes, so watch my blog 😉
You prove your skills and talent on a resume, but a blog gives you the freedom to express your personality. In the web industry personality can really make you stand out in the crowd.
