I signed up for Google Wave! Now I have to hope I'm one of the 100,000 chosen ones and wait for October and then I might try it out.
What is Google Wave anyway? No one exactly knows, but Gina Trapani said in less that 140 characters:
Simplest terms: Google Wave is Gmail on crack. Imagine Gmail, Google Talk, and Google Docs in one big inbox.
Sounds cool. I'd love to try that! Especially if I get to give improvement suggestions when it comes to usability.
