While about 6,000 developers got their hands on Wave Monday, Google will open its Google Wave service up to the public beginning on on Sept. 30, the company said this week.

About 100,000 users to get Google Wave this fall. A post on the Google Wave developer blog says the company isn’t planning to open it up to everyday users until September 30th.

Is it better than e-mail and instant messaging?
How about wave as a collaborative editor?

Seems, these questions can wait till September.
