Previously, the newest version of Skype for Windows which is version 6.0 has the Windows Live Messenger support but to make things even faster and more fluid, it seems that Microsoft has decided to ditch Windows Live Messenger in favor Skype next year. Now, there’s also the Linux version of Skype that is based on Windows version of Skype 6.0.
Interestingly enough, the Linux version of Skype is multi-arch friendly. This means, 64-bit users can install the 64-bit version of Skype on the 64-Bit Linux OSes. Unfortunately, there are flaws for the 64-bit version of Skype for Linux compared to 32-bit versions.
