I surfed the web and discovered WordPress.org for myself. First, I didn’t like the idea of having to have to back up and put on new releases for a blog. I was intimated by the responsibility and thought it would be too time consuming, not to mention all the problems that can happen along the way with open-source software. However, I found that the positives outweigh the negatives. Plus, WordPress has come a long way as far as going beyond blogging. It can now be used as a full content management system. This gives your users the freedom to update their own information. Plus, there are so many wonderful themes that are very flexible to customize for your clients.
Even though WordPress.com, is also very user friendly, easier to use, plus you didn’t have the headache of maintaining it because it’s all done for you online without even having to sign up with a web host. However, there are limitations as far as the design flexiblility, but if you want a website fast, this may be for you.
