Often I recommend people to start a blog. Not so much to write personal stuff, but rather as a Self marketing tool. The general response are very critical towards the blog phenomenon. Usually people equal blog with online personal diaries there people only talk bullshit. Many good Swedish examples. But I view blog only as the technology used to easy publish text. Its free and easy to setup and then administrate with designs.
Aaron Wall, the man behind SEObook.com, have posted a great video, explaining why anyone should start a blog, if your serious in your web business. Blog is a perfect tool, not just for companies but for people who want to market them self. Lets just hope that the regular media, advertiser and corporations aggravate the value of blogs by using them wrongly.
