As you know, I am very interested in the google wav API and gadget/extension development, and as the service is not yet provided by Google, I had to request a preview developper account from the google code project page.
I am aware this will take some time, this means I will not be able to tell you soon how great is google wave, but almost no public information is available anyway yet, si I guess we will have to wait some time.
I hope you bookmark the blog to be "in the know" when something interesting will happen here.
See you later.
