Looking at Lady Gagas twitter (10m followers, average celebrity) when she tweets a link it gets ~100,000 clicks, 1%, so to suggest 3.6 million timelines is 3.6 users "reached" (where reached means actually engaged) is silly, it'll be closer to 36,000 assuming Lady Gaga is a good example. I have ~600 followers on Twitter and when I tweet a link, it usually gets ~80-100 clicks on it, well over 1%. Just because Lady Gaga doesn't have a high rate of people clicking links, doesn't mean that it applies across the board.
