Back in the early days of Google, I had to wait to get a gmail account invite and I'm don't really recall how I got on Orkut, but I bet I had to find me an invite too...
Anyway, Google Wave could be extremely interesting and the I/O presentation of it was fabulous, and better than the only text based Google Knol information presented some year and a half back.
Many of us have a feeling to already know something about Google Wave even before testing it ourselves.
