volubility

God help any of us if the police can use this kind of "evidence" to make us a suspect in a murder: 'Suddenly, the very qualities that had endeared Joe to his community — his demonstrativeness, his warmth, his volubility — were cast in a different light. “Homo tendencies?”

When the signal was given, the students knelt before Mezzofanti and then rose quickly, talking to him 'each in his own tongue, with such an abundance of words and such a volubility of tone, that, in the jargon of dialects, it was almost impossible to hear, much less to understand them.' Mezzofanti didn't flinch but 'took them up singly, and replied to each in his own language.'

In my not-so-humble opinion, if you have the time and volubility to constantly make long, good comments on popular posts, you'll be rewarded. But if you don't, because the vast majority of comments will net you nothing, you'll get more by optimizing for quantity and being first to the scene, hoping for a small number of posts and comments to semi-randomly get a large fraction of the karma, than pre-selecting for quality.
