1/8 video callers

Hmmm … i don’t know what to think about it but i read this in the Associated Press (again some numbers):
Jonathan Christensen, Skype's general manager for audio and video, said a quarter of all Skype calls have at least one talker on video. The service claims 246 million users

Let me correct this somewhat:

• If it is true, at least one out of 8 callers uses video!
• 246 million “registered user accounts” … NOT users, probably only 50 million users!

I repeat why it is “USER ACCOUNTS” therefore why there are less active users than registered user names:

• lost password, and therefore inaccessible user name, therefore the need to create a new user name
• testing Skype, and abandoned use of the user name
• spare user names, registered for alternative or future use (i have several!)
• the owner of the user name died (yes, this also happens!)
• the person switched to another VoIP tool
• the person registered a temporary name for a temporary past situation
• spammers also register multiple usernames to "attack" their victims
