Speaking of Goolge Wave it offers the functionality of an email program , instant messenger ,a collaborative document sharing and editing tool. The concepts aren’t new just that the many existing concepts have been married together to create a new experience.In Goolge wave anyone can be part of wave and people could be added to an existing wave . Any part of the wave could be edited by anyone within the wave.
This is radically different and the whole beauty of it is that all the changes made is archived and we could view the changes made to the wave giving us an explanation of what happened to wave ,when it happened and by whom. This makes wave a perfect tool for collabration and communication among office environments .We can reply to messages within a conversation string and we also could reorganize conversations but as I said earlier all these changes are archived for future reference. Simply speaking it offers wiki style functionality.
In the existing communication model all communication tools exist individually. With Google waves all that can be brought under one single platform. Extensions can be used to iplement Twitter and Facebook extension thereby enabling communication through all potential channels in the web under one single tool. In plain speaking it offers a better communication experience than the existing tools by bringing it all under one paltform.
There is also a playback feature which enables someone who has joint lately to see how the whole conversation developed. This actually helps him to be a part of the wave much better.
