On October 7, 2009, I opened my sandbox account and found an invite for the Google Wave preview which has been sent last week. I have been waiting for an invite through my mail and I did not realize they would simply send a "wave" on my account.
My Google wave account is firstname.lastname@example.org. As of now, I only have 1 contact and hopes to add more friends soon.
I have already tried using Google Wave using my developer sandbox account with some of the people from Google Technology Users Group Philippines.The persons who I had time to try out Wave with are Aileen Apolo, Marc Lester Tan, Roger Filomeno, Alvin Gamboa, Nikki Ramirez, and Randell Benavidez. Randell posted it in his Dev Blog.
However, the real Google Wave is very much different from the Wave I had experienced trying out with my developer sandbox account. I am hoping to see more of Google Wave and try out if I can make a Wave gadget or robot in the near future. I am keeping my fingers crossed...
