Corollary: The more people that comment, the higher the budget of the think-tank whose job it is to make counter-comments (either via bot or shill). It's a difficult fight when any effort you put forwards can be matched with a few dollars.
Dollars have the disadvantage that they can only be coarsely targetted. A timely, laser focused argument will always beat whatever keywords Kellyanne Conway happens to be spamming millions of viewers with today. Campaigns at that scale just can't scratch the same itch. The trouble is laser targetted arguments take much more time to formulate, so you have to use them sparingly. The tau comes in handy.
