Just spent 40 minutes calling California for an interview. Normal phone charges would have made this an expensive conversation. With Skype, it just cost me 52 p. Quality was great.
This followed on from a conference call with the fellow organizers of the Sparkling wine symposium, which we also did on Skype, and which cost nothing.
Just another example of how the internet has changed the way that we communicate. Some people make use of it; many don't.
