CBC reports today that Nielsen Research has found that despite the massive influx in Twitter - helped along the way by Jon Stewart, Oprah, Ashton, and CNN - the massive abandonment is even more interesting.
A full 60% of people who visit Twitter each month will never return again.
That is an improvement from where it was (at about 30%) prior to all the celebrity attention.
In contrast, MySpace and Facebook each sit around 70%.
(In related news ... I recently blogged about the "Coming Death of Facebook", which was an opinion piece on the CTV news site.)
