PavelDurovvKontakteRussian social network vKontakte shares much in common with Facebook, including most of its basic design elements, but its CEO, Pavel Durov, is not the biggest fan of his counterpart in Menlo Park, Calif., Mark Zuckerberg.

IDG News Service reported that Durov responded to remarks Zuckerberg made in the past about VK by saying:

Mark underestimates VK. He doesn’t use it very much. VK is faster, easier to use, and has more functionality.

And when asked whether Facebook should strengthen its encryption technology in the wake of the U.S. National Security Agency’s Prism online surveillance initiative, he said yes, according to IDG News Service, adding about Zuckerberg:

But he might have other priorities.

Speaking of Prism, Durov was complimentary toward Edward Snowden, who leaked information about the initiative, saying:

He’s had to sacrifice a big part of his life to let us know that we’re being spied on.
