To blog or not to blog

I am not sure I understand the concept of blogging. As it's grown ever popular in our internet dominated world I have shied away from creating a blog, not sure what it would benefit and not sure the purpose. Yet after speaking with yet another dedicated blogger, I decided it was time to give it a try. I'm not sure what I'll write about, or how long this may last, but as a writer, I guess it's good to explore different styles of writing. So here's to an attempt, we will see where it goes.
