Playing with sound statistics

Don't get me wrong I love Skype, but the hype on many web pages is "40 million registered users of Skype". Now on-line I only ever see 1.5 million - and I am on-line with skype 24/7. Which means there are 38.5 million dissatisfied ex-Skype users out there.

So who is right - the 1.5 million die-hards like myself, or the 38.5 million who went away?
