HOW TO: Leverage Social Media for Career Success
"Aside from social networks, I highly encourage you to have your own personal digital asset.
This could be either a blog or a traditional website registered under your name or the topic you want to own (with keywords).
For blogging, use either WordPress.com/.org, Bloggerblogger reviews, TypepadTypePad reviews or TumblrTumblr reviews.
For traditional websites, use a host such as Bluehost, Godaddy, or a free host like Bravenet."
