A few months ago LG15Today, along with every other blog in the universe broke news of Google's next big thing Wave. Well, the fine folks over at Mashable have compiled a very nice break down of Wave's features.
Some of the more interesting and useful functions are the ability to embed waves directly into websites, on the fly translation, and the ability to play back past waves. Google announced recently that starting September 30th 100,000 lucky users will have the chance to beta test Wave. In order to be one of the lucky few, one has to sign up at the Google invite page.
