While we have evidence that the number of Facebook users is steadily declining, is doesn't necessarily follow that we should "expect Twitter and other social media sites to follow suit over the next few years." The loss of users on one particular networking site (due to privacy issues, boredom, excessive ads) shouldn't be projected to reveal a general trend. For example, soon after Friendster and MySpace began their time-on-site declines, Facebook's exploded. Currently Ask.fm is in a growth phase, as is Instagram, and thus we can't extrapolate any broad trends from one example. Also, I don't know if the data from Facebook was filtered to extract users who'd set up duplicate or fake accounts. FB's crackdown on fake users may have reduced their user counts.
