The next graph represents the number of concurrent Skype users online on September 09, 2013.
see my post.
But, what surprised me is the following fact: Monday is usually the peak day in users online, but after the “false outlook induced growth” of end of August we had a quite significant downward trend (rounded numbers):
- Monday, September 09: 62 million
- Tuesday, September 17: 62 million
- Monday, September 23: 58 million
- Monday, September 30: 58 million
