Microsoft has just announced that you'll soon be able to make video and voice Skype calls from just about any computer with a web browser. Skype for Web (beta) calls will work on Chrome, Safari, Firefox and of course, Internet Explorer, with the addition of a "small plugin," at least for now. Microsoft said that it'll eventually work natively on browsers without plugins or downloads once WebRTC is more widely implemented. That'll be especially handy for users with no access to the dedicated app who may want to chat with or message friends from, say, an internet cafe in a foreign country.
