"Effort" is not a measure of the magnitude of how much a comment contributes to a discussion. Just because I don't feel like writing a dissertation does not mean my comment doesn't contain a worthy discussion point. Even if true, it doesn't explain why it suddenly started happening some weeks ago and wasn't happening before.
