Writing good bug reports is a skill that is, in my experience, only taught to software testers, and even then only informally. My first job out of college was Software Test Engineer (STE) at a large software company that was plenty mature enough to have formal training around these things, and yet during my first week on the job my mentor instructed me to query the bug reporting system for bugs written by particular STEs on our team because they were known to write well-structured, quality reports. This was not a terrible way to learn how to write a good bug report -- I learned a lot from this exercise -- but it's not exactly a good way to evenly distribute such knowledge across entire teams or companies.
