WordPress is a blogging platform that is very flexible and allows you host a site on wordpress.com or on your own domain name that you already own. There are other blogging sites such as Tumblr and Blogger which are great for getting a blog up and running in a short amount of time but from the entrepreneurial perspective WordPress is the way to go.
If you do not have a domain name yet and are new to blogging, go to wordpress.com and start a blog. Don’t get bogged down worrying about content or having a topic you are passionate about yet. Get started just so that you can learn how to do routine tasks such as adding a post, adding plug ins, and changing your theme. Check out the following links.
