Microsoft has just opened up Skype to work your favorite web browsers. This is ideal for those that Skype from their mobiles or those that find themselves in an internet cafe or computer without Skype installed and setup.
It only entails you visit Skype.com or web.skype.com, install the browser plug-in then join the conversation. The Skype for Web is still in beta stage and currently only available for users in US and UK. It will subsequently be rolled out for users worldwide.
