I do – but I'm an academic, not a software engineer. Spreadsheets are abused and don't make a formal distinction between analysis and data. I've seen many horrible, horrible things happen because people used Excel when they really, really shouldn't have. Intelligent biologists reinventing numerical integration (badly) in Excel, for example (with huge floating point errors, often comparable to the size of the change they are looking for biologically).
