I thought everybody was being overly grouchy about the survey, and then I took it. I didn't like it, either. The survey was overly repetitive, and asked questions that just weren't interesting or of any seeming value.
Yes, I use digital folk music resources constantly. Online music research is one of the main things I do with my time. I was associate editor of a songbook with 1200 songs, prepared entirely on Google Docs and researched at Mudcat, Ballad Index, and Roud. I'm the music editor at Mudcat, and that's where I do my research. I listen to music on Spotify.
I find Facebook to be a poor medium for research because it's hard to find the information that was provided in the past - but Mudcat is an ideal tool for collaborative research of songs.
