There was a mad Skype craze on Secondlife just before Sl integrated voice into everything, which pretty much stopped all of the people I used skype with from using it anymore. I am home now so infrequently, and so busy when I AM home, that the once useful chat function of Skype no has no value for me. At this point ther are far better IP telephone services available anyway. Just browse around the internet for news about Skype, you will find the vast majority of everything dates from 2006.
If you get grandcentral / IPKall & Gizmo5 and use them together, you now have the ability to call anywhere you want with your regular phone for free ad infinitum.
