I just LOVE Skype. I started using their service late 2003 or early 2004, I can't recall.
Their ability to make things easy and straightforward is one of their biggest strengths. No nonsense. And when Skype became capable of handling calls on legacy telephony services, I was stunned with their design of the software: they were able to make full use of my existing experience and user education with a phone!
I know this may sound naive, but still I wanted to praise those guys for their excellent design. Small "details" were clearly thought through and everything works smoothly, including when I am calling a service provider who greets me with an IVR system. Great work! Design is great at Skype and marketing communication is as great: I just love their counters on their web site with numbers of downloads and minutes served.
Skype is stunning. Praise to their people for their accomplishment. Yet another indication that it's all about talent!
