Basically, if someone can crack the Skype cloud and get data, in theory they will be able to find out who is on, when they are on, who they talked to, how long they talked, and I wonder if the text is En Clear, not EnCrypted.
While this is one more for the technology friends I have, I have to think back to when others shared other concerns about Skype about a year ago.
I hope some of the more technically minded bloggers get into this and see if there is a real reason to be concerned, or better yet to see if Skype has a response.
