When creating a blog you must know upfront that it will take you about an hour to setup when you know all the steps. I do them faster if I have the content and images that I want to include. The beauty of blogs is that you can update them online, as long as you have internet connection. No need for expensive web design software.
You need a visual sitemap to effectively plan ahead. With a visual sitemap, you will see exactly how your structure is developing. You can then have a clear understanding of how to proceed, what to correct or improve, and what areas are best serving your site. A clear overview of the project will prove to be invaluable.
