How Important are Status Reports?

I had a comment from a client recently that I hadn't sent any status reports during the course of a project. I don't usually send them for small projects because I just don't feel they're necessary. If you are dealing with a brand new web writer or one who isn't used to meeting deadlines, etc., I can understand asking for status reports just to make sure they are actually doing the work. But, from a professional with nothing but good feedback from countless clients, what's the point?

The only time I send status reports is when it's a large project or when the deadline is long or indistinct. For very large projects, a quick report is warranted to reassure the customer. For long or vague deadlines, I like to send one to tell them exactly when it will be finished. If it's a project consisting of five or 10 articles, um, no. I have my deadline. I have my instructions. I will write the articles and turn them in when it's time. There's no need for hand holding on either of our parts. I'd like to know if anyone else feels like they have to send constant, pointless updates for small projects.
