The Chinese market is very, very unique.

We have 2 million users in the U.S. and about 13 million worldwide in more than 200 countries. We're getting 80,000 new users each day. And more than half a million people are connected via Skype at any given moment.

We also have a conference call feature where up to five people can talk on one Skype call.

You shouldn't be afraid of failure - when something fails, you think, 'What did I learn from that experience? I can do better next time.' Then kill that project and move on to the next. Don't get disappointed.

We have just started, and if you compare the number of people using Skype to the number using a telephone network around the world, we're still just starting.

The telephone is a 100-year-old technology. It's time for a change. Charging for phone calls is something you did last century.

They also can combine voice with instant messaging and online file sharing.
