Skype Dialtone: 22 million online.

22,268,233 Skype clients logged in at the same time, up from the 21.5 million record last Monday.

Here's the updated trendline going back from the beginning.

While a straight line explains 97% of the data, a polynomial regression fit gets us to 99%. The curve guesses 26 million people online at the same time by year's end. This on a base of more than 520 million user accounts.

My crude estimate puts active Skype users, people who log in over a two week period, about 132 million. This allows for different time zones and for people who use Skype for very short sessions during a month.
