I don't know how many of you guys have ever actually contacted RMS, but whenever I did, his answers were quick, polite and to the point. Anecdotal, I know...
In 1998 I wrote some documentation and offered it to the GNU Project. To my surprise, I got a reply back from Richard directly. He was very pleased that someone had written such documentation and offered it to them. (I remember him using the word "Hooray!")
However, in retrospect, what I wrote was pretty poorly written. It was my first major attempt at documentation, and Richard critiqued it heavily. I felt very hurt, but he was probably kinder than he needed to be given the low quality of my work, and, more importantly, he was correct. Once I got past feeling hurt, I learned a lot from his critiques. I essentially got free training in technical writing from Richard, and I look back on that as one of the more awesome moments in my life in software.
