Automator - Yay or Nay?

A post yesterday at MacSlash asking how useful Automator really is inspired me to bring the question to the TUAW audience: do you use Automator? Do you find it useful or useless? I know plenty of workflows make their way through the TUAW postings, and I'm personally a huge Automator fan and user for some of my daily work, but I'm wondering about the rest of you. Have you already deleted the application, or are there workflows with a reserved space in your startup items? Sound off in the comments.
