Business 2.0 lists the Top web 2.0 sites developed outside of the United States.

It is interesting to note that 19 out of the 31 listed have some element of social media in them. Question is, how hard is it to add some social to your web app? For example, could Joost add a “watch what your friends are watching” function to their app?

Oh, and Singapore darling Bezurk is one of them, as well as mTouche from Malaysia.
