I figured it out because you cross-post a lot. When Eddie Van Halen died, you talked about your favorite VH song here, and then later in the day on Prindle's Facebook, I was like "Hey! This guy has the same favorite VH song as Bill's! ... OHHHH."
For what it's worth, I don't post much, but I like Prindle's Facebook a lot, even though he does the same OCD posts over and over. There's just a great wealth of opinion and knowledge in the comments, and it's slanted more toward the kind of rock music I like. Plus, people like Lou Barlow and Shannon Selberg comment on stuff!
