Google has unveil the next product they will launch later this year. It’s called Wave and it’s a communication protocol. It’s like the email of the 21st century, but much more than that. Wave is a collaborative product. The waves are communication objects, both conversation and documents, allowing people to almost instantly communicate on the web.
Waves allow people to send emails, but do it in an instant messaging style, sharing media like pictures and movies and being able to see live what the others are typing or sharing, and playback the entire conversation.
Wave is also an open source platform for building blogging sites or discussion groups. It provides APIs for collaboratively editing documents, building games (and playing back the moves), integrating with other communication systems (like twitter) and others.
To see what wave actually is, see this preview.
