Google Wave! I am Coming
Finally after waiting so long to get the Google Wave invitation, this morning I get the invitation. An email from wave-noreply@google.com that contains activation link to activate Google Wave account.

Yes, I just click the invitation link and my Google Wave account immediately active ;).

If you are new about Google Wave, I recommend you to watch Google Wave Developer Preview at Google I/O 2009 below.
Or you can watch short video about Google Wave: 15 features if you want to know brief description about Google Wave powers.
I am sorry if I too excited to tell you about Google Wave, don’t worry mate, if you don’t have Google Wave account yet, you can request using Google Wave Developer Sandbox Account Request or you can ask me to invite you, just simply put on comment below, and I will happy to invite you.
I have 20 invitations left on my Google Wave account. Even invitations will not be sent immediately, as Google said, but I hope it will be faster than regular account request.
For those who have Google Wave account, browse to http://wave-samples-gallery.appspot.com to get dozen of robots or gadgets for your Google Wave. Happy waving!
