Blogs can create and audience, captivate readers and create a buzz in the social media world. They can also become your website; in fact many news websites have their origins as blogging technologies.
Setting up a blog is easy, and choosing a theme and relevant topic can be difficut, but keeping it focussed and up-to-date is a real challenge. Without connecting to bloggers, refining material and promoting your page there will be no success in a blog.
