From the Compete blog:
There is certainly something magical about reaching 20 million. Web 2.0 darlings, also prime acquisition targets – Digg and Facebook both crossed this milestone last month.
* Digg edged out Facebook, with 2.3 million additional unique visitors
* Facebook is growing 3x faster than MySpace (on a percentage basis)
For what it’s worth, Quantcast says Digg has 6.9mm in the US…
Surely that’s because everyone’s already got a MySpace… whereas ‘this facebook is the next big thing’ amongst the masses.
