Run Drupal

I recently have been working on a site that doesn't use Drupal but instead uses a very simple inline CMS. The site is called Taking Back Ground Bozeman. It is the home page for a ministry called Taking Back Ground which focuses on helping people who are struggling with addictions to pornography or similar issues. Here is a summary of what the site is about:

We live in a hyper-sexual culture. A sin that often takes us out is lust, especially in regards to pornography and sexually explicit images in the media. Because this affects so many men and women in the church a ministry was started to focus specifically on helping people who have been affected by this. This ministry, Taking Back Ground, is a weekly meeting to help people overcome this sin. It is designed for anyone affected by pornography: this includes users who have “dabbled” or who feel addicted. It is also a place for spouses, parents, young adults, and anyone who has been affected.

The nice part with the site is that it is easy to update. Obviously it doesn't have the kind of power that Drupal does but at the same time the site will probably never need these advanced features. What do others think? Do you find yourself using Drupal exclusively? Or have you found uses for other, more "lightweight" solutions. I'm wondering if this will come back to bite me as we decide we do need some of those extra features.
