Rather than sending a boring paper CV out, send recruiters your blog address so that they can find out what sort of person you are and what experience you have. Artists can also put their work online for their visitors to see.
Fashion designers who haven't got an outlet can also put their creations on a blog to attract customers to their self-created shop window. And if you can't find a publisher for your novel, why not put it on line so that your life's work gets read and doesn't stay locked in a drawer to gather dust forever? Internet users can then access unpublished works and publishing houses looking for new talent might just stumble upon the gem they were looking for.
Blogging is also a great means of networking. Looking for a job in marketing in Newcastle? A visitor to your site reading your comments on the latest film might just be able to put you in touch with her boyfriend who knows someone. Word-of-mouth works on the web too!
