While reading on some security questions on skype. I found an interesting presentation from Ebay on why it acquired skype and what it plans to do with skype.
This is a very interesting presentation. It is interesting to note that of the 60 million skype users there is only a 1% overlap on users that use ebay. This means ebay has the ability to add 54 million users to its list of members. This is very good news for ebay sellers!
