Both of these software packages are open source and written in PHP. Which one is the one you choose? That depends one your time and objectives. WordPress is exclusive and limited to make Blogs. It is actually a very easy software to make blogs as it comes with a predetermined blogging visual configuration, ready to use. Drupal instead, is not only to make blogs but to make any content system, like a video tube or an online newspaper. Of course, that means that it will take more time to configure it and actually “code” in order to get your results. So to sum up, For WordPress you will have a blog very quickly with almost no programming skills required. For Drupal you need more time and programming skills. How much effort are you willing to put here? No matter which path you choose, there is gain in experience in Drupal for the time invested, and perhaps you come up with more ambitious ideas for your next web hosting project! Think it for a couple of hours but not for more. Those hours could be useful in your project. Good luck!
