I have some experience with Drupal, but for the most part, I feel in over my head at times. Drupal can be used as a hybrid, meaning it can be a website AND an interactive forum.

The set up is simple and intuitive and is just a matter of adding the Drupal pack and some add-on modules into your database, but when little quirks and issues pop up, you have to know how to fix them. Sometimes this involves going into your database and fixing the problem by hand.

Overall, I've had success in using this for informal, family blogging. I've tried to use it for commercial purposes, but unless you have software developing / coding experience or want to learn, I wouldn't dive back in.
