I've never used Skype. Is there something it does better or differently than any other VOIP/messaging client that's made their poor Linux support such a popular issue, other than it was better before Windows bought it?
My current daily means of communication on Linux is Google Voice/Hangouts, but I've also used others over the years, like GnomeMeeting/Ekiga, TeamViewer, and TeamSpeak. They've all worked fairly easily and without issue. With all the options, could someone explain why Skype matters?
There is one thing that Skype is particularly good at that other VoIP/messaging clients aren't: talking to users who have Skype accounts. Your question is little different than suggesting there are many alternative social networks to Facebook, so why don't people just use those instead?
