I went from a large company, developing applications for internal customers (i.e. other employees), to a small company with external customers. It's been very difficult to get feedback from my new customers. At the big company, I could always meet face-to-face with them, and had some leverage if (like everyone else) they didn't feel they had the time to provide the feedback.
Any suggestions on how to get that feedback? Talking to the company Help Desk folks is one option, but to me that's second-hand info at best.
