When you blog with WordPress you can create users so that you have many people adding content for you so it's not just one person. I have created many WordPress blogs that I do not even touch anymore, someone else is responsible for the content.
All the changes can be made by logging in through your own website. You do not have to have website software like Dreamweaver or Frontpage, you do everything online. So if I am on vacation and I need to update my site I can do so from my hotel by logging in online and making the changes.
The best thing in my opinion about WordPress is that you can schedule posts to be posted automatically. So let's say I write three posts in one day but I don't want them to publish all in one day, I can schedule them to post throughout the week and they will. This is how you work smarter and not harder. Visit the website and get to know about wordpress booking plugins, and windows xp your connection is not private.
