I think there are probably a number of reasons. It’s difficult to care about education when the world has turned upside down. I think the part of the drive to engage early on was the newness of it. Now i think people are a bit more careful about what they join in with. I think that places like twitter aren’t as safe as they once were when they were less popular. Maybe some of those, maybe others. Also… I’ve been doing this a long time, I’m probably not as interesting as i might have been 🙂
